3. Configuration Procedure
This paragraph describes the installation procedure for the HSS8 Windows NT 4 Software Driver.
3.1 Installing the Software Driver Files
Unzip the file “hss8ntvxyz.zip” to any suitable folder on your local PC Hard Disk Drive (HDD). You must have
administrative privileges on the PC. Run the application “Setup.exe” (Figure 1). All the software driver files will
be extracted to the required locations, i.e. the software driver file will be stored in “WINNT\system32\drivers”,
the control panel applet in “WINNT\system32" and the flash update application in “Program Files\C2I2\HSS8”.
AsthisisnotaWindowsDriverModel(WDM)driver,Windows2000andXPwillreportdeviceconflictsbetween
the software driver and an “Unknown PCI bridge” device. This is due to the NT software driver not supporting
plug and play (PnP).
3.2 Special Instructions for Windows 2000 or XP
The software driver can be installed as a legacy software driver under both Windows 2000 and Windows XP.
However, to obtain optimum performance it is recommendedthat the "Standard PC" HardDisk Drive (HAL) be
used. For detailed instruction on how to install the "Standard PC" HAL refer to the Microsoft Knowledge Base
articles : KB237556, KB299340 and KB309283.
Duringtheinstallation ofWindows2000orXP, press theF5keywhenthe text"Setupis inspecting..." appears.

4. Application Program Interface (API)
The HSS8 Windows NT Software Driver complies to most of the Windows 32 API for serial devices, i.e.
channels can be opened and used in the Windows HyperTerminal application. Refer to the Platform SDK in
[2.1.4]forthecommunicationsresourcedocumentation.TheserialfunctionprototypescanbefoundintheSDK
file “winbase.h”.
The device channels are named HSS8_1 to HSS8_12. HSS8_1 to HSS8_8 are the SCC channels, HSS8_9
to HSS8_12 are the SMC channels.

4.3 Function Limitations
Not all settings are supported for each serial function. This paragraph will mention all the exceptions.
4.3.1 ClearCommError
Only CE_FRAME and CE_RXPARITY are supported.
4.3.2 GetCommMask
Only the EV_RXCHAR event mask is supported.

CCII/HSS8/6-MAN/004 2009-08-31 Issue 1.2
CH8MAN04.WPD Page 7 of 26
4.3.3 SetCommMask
Only the EV_RXCHAR event mask is supported.
4.3.4 WaitCommEvent
Only the EV_RX_CHAR event mask is supported.
4.3.5 Overlapped Writes
When a port is opened in overlapped (non-blocking) mode, overlapped writes might not behave as expected.
An overlapped read will return immediately, and the event will be signalled once data has been received. For
an overlapped write the function will not return immediately. The HSS8 Windows NT 4 Software Driver has to
send the data to the adapter, where it will be transmitted. This transfer does require a finite amount of time.
ChangingtheHSS8WindowsNT4SoftwareDriverarchitecture tomatchtheoverlappedreadoperationwould
degrade its throughput performance on transmission.
4.3.6 FlushFileBuffers
Not supported.
4.4 Structure Limitations
Not all the fields of the serial structures are used by the HSS8 Windows NT 4 Software Driver. This paragraph
will mention all the exceptions.
4.4.1 COMMCONFIG
dwProviderSubType:none ofthe typesmakesprovision foradevice thatisboth RS-232andRS-422 capable.
No provider-specific data is supplied.
4.4.2 COMMPROP
dwProvSubType, dwProvSpec1, dwProvSpec2 and wcProvChar are not supported.
4.4.3 COMMTIMEOUTS
ReadIntervalTimeout is not supported. The write timeout value is used by the HSS8 Windows NT 4 Software
Driver to flush its internal transmitter queue. The internal queue is only used when one byte is transmitted at
a time.
4.4.4 COMSTAT
Only cbInQue and cbOutQue are supported in this structure.
4.4.5 DCB
The following fields are not supported :
fOutxDsrFlow, fDtrControl , fDsrSensitivity, fTXContinueOnXoff, fOutX, fInX, fErrorChar, fNull, fRtsControl,
fAbortOnError, XonLim, XoffLim, XonChar, XoffChar, ErrorChar, EofChar, EvtChar.
StopBits of ONE5STOPBITS is not supported by the HSS8 Windows NT 4 Software Driver.
Note : The XON, XOFF flow control is not supported by the HSS8 Windows NT 4 Software Driver. To
use no flowcontrol, the fOutxCtsFlow field must be set to FALSE.

5. HSS8 Windows NT 4 Software Driver Protocol Settings
The HSS8 has eight serial communications controllers (SCCs) [Channels 1-8] that support UART and
HDLC/SDLC protocols, and four serial management controllers (SMCs) [Channels 9-12] that support only
asynchronous UART.
The control panel applet allows the user to set all the protocol-specific options available on the
HSS8 communication controller chip (the MPC8260 PowerQUICC II™). For available options for each of the
fields, see [2.1.1].
This section details the information used by each protocol and explains the use and limitations of every
member.
5.1 Protocol Selection
Each Channel must be configured to use a protocol.
Protocol :
UART
HDLC
BISYNC
SMC_UART
The protocol settings for the device can be set through a control panel applet. Access the applet by clicking on
the Start menu and selecting the Control Panel from the Settings option. Click on the icon shown in Figure 2.
Figure 2 : Applet Icon
5.2 Using the Control Panel to Change Channel Settings
The control panel applet selection boxes list available options for the specific protocols. Options that are not
available for the selected protocol are grayed out. All the options (including the options in the Advanced
dialogue) must be entered to create a valid protocol setting. Always click the Apply button before closing any
of the dialogue windows. The settings are applied to the HSS8 Channel when it is reopened.
When “Lock Settings” is checked, all requests via the Win32 API will be ignored. Any change in baud rate or
parity will then not be updated, the HSS8 Windows NT 4 Software Driver will keep the setting as specified in
the control panel. When the settings are not locked, the baud rate, etc. may be updated via the Win32 API
functions.
When using the HDLC or BISYNC protocols, it is recommended to use the “Lock Settings” option.
The settings are stored in the Windows registry, under the keys :
“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HSS8\DeviceX\PortX”

5.3 Using the Control Panel to Obtain the Current Version Information
Clicking on the Information icon near the bottom of the dialogue screen will display the HSS8 Windows NT 4
Software Driver information dialogue shown in Figure 3.
The Driver version is referring to the HSS8 Windows NT 4 Software Driver itself. It has the format X.Y.Z. A
changein Xwould indicatethat theHSS8 Windows NT 4 Software Driver has an added feature. Ywould mean
that a new software driver engine is used in the software driver. Z indicates any corrections to problems in the
HSS8 Windows NT 4 Software Driver.
The Engine version must be identical to the firmware version for all cards in the PC. Normally this would only
be different when the software driver version is checked after a firmware update and the software driver itself
has not been updated.

5.4.1 UART Protocol Information
Name Options Description
Baud Rate 1 200 - 1 Mbit/s (RS-232)
1 200 - 16 Mbit/s (RS-422/485)
Any values permissible.
The equation to calculate the actual baud rate for asynchronous
UART is as follows :
Actual baud rate = 100 MHz / 16 / ROUND (100 MHz / 16 /
Desired baud rate)
The equation to calculate the actual baud rate for synchronous
UART is as follows :
Actual baud rate = 100 MHz / ROUND (100 MHz / Desired
baud rate)
Where ROUND () implies that the result is rounded to the nearest
integer.
Used to specify a single baud rate
for both transmitter and receiver.
Units in bit/s.
Clock Source CLOCK_DEFAULT CLOCK_DEFAULT connects Baud
Rate Generators (BRGs) [1 - 4] to
Ports [1 - 4] and Ports [5 - 8].
For synchronous UART :
When transmit clock is set to
CLOCK_BRG[1-4], then receive
clockisstillsettoCLOCK_EXT[1-4]
for Ports [1 - 4] and Ports [5 - 8].
For asynchronous UART :
Transmit and receive clocks can be
set to one of CLOCK_BRG[1-4] or
CLOCK_EXT[1-4].
Note :
There are four BRGs and four clock
input pins per PowerQUICC II
processor.
CLOCK_BRG1

Freeze Transmit Pause (freeze) transmission.
Transmission continues when set
back to normal.
RX with no stopbit If set, the receiver receives data
without stop bits.
Sync. Mode Select asynchronous (normal) or
synchronous mode.
Disable RX while TX Enable (normal) or disable receiver
while transmitting. Used in
multidrop mode to prevent
reception of own messages.
Disable Parity
Checking Enable or disable parity checking.
TX parity, RX parity ODD
LOW
EVEN
HIGH
Receive and transmit parity. Parity
will only be checked if parity is
enabled.
Diagnostics Mode NORMAL Normal operation. Use this
for external loopback.Set diagnostic mode.
External loopback - RS-422/485 :
Connect TxD+ to RxD+, TxD- to
RxD-, (CLK_OUT+ to CLKIN+ and
CLKOUT- to CLK_IN- for
synchronous mode).
External loopback - RS-232 :
ConnectTxDto RxD,(CLK_OUT to
CLK_INforsynchronousmode)and
RTS to CTS and CD.
LOOPBACK Internal loopback :
TxD and RxD are
connected internally. The
value on RxD, CTS and CD
is ignored. The transmitter
and receiver share the
same clock source.
ECHO The transmitter
automatically resends
received data bit-by-bit.
LOOPBACK_ECHO Loopback and echo
operation occur
simultaneously.
Max. RX Bytes 1to16384(default) Maximumnumber of bytes that may
be copied into a buffer.
Max. Idle Characters 0 to 16 384 (default) Maximum idle characters. When a
character is received, the receiver
begins counting idle characters. If
max_idl idle characters are
received before the next data
character, an idle timeout occurs
and the buffer is closed. Thus,
max_idl offers a way to demarcate
frames.
To disable the feature, clear
max_idl. The bit length of an idle
character is calculated as follows:
1 + data length (5-9) + 1 (if parity is
used) + number of stop bits (1-2).
For8 databits, noparity, and1 stop
bit, the character length is 10 bits.
Break Characters 0-2048 Numberofbreak characters sent by
transmitter. For 8 data bits, no
parity, 1 stop bit, and 1 start bit,
eachbreak characterconsistsof10
zero bits.
Address1, Address2 0x0000 - 0x00FF Address in multidrop mode. Only
the lower 8 bits are used so the
upper 8 bits should be cleared.
