1. Function Overview
S1R72U16 Development EPSON 1
Support Manual (Rev.2.00)
1. Function Overview
This LSI includes two functions to support product (system) development. They are controlled by a PC via
the serial interface.
•History display function
•USB logo certification support function
The History display function enables the viewing from a PC of various details, including IDE/USB status,
detected USB device type, transfer history, and error information. It also enables connection verification
between the main CPU and the LSI, as well as simple debugging using transfer history and error information.
The USB logo certification support function is used to switch to the test mode corresponding to the electrical
test as part of certification testing. For detailed information, refer to the S1R72U16 Embedded Host
Compliance Guide.
Note the following precautions for history information.
•HS devices connected via an FS USB hub will be recognized as FS devices, not HS devices.
•Only Bulk Only Transport Mass Storage Class devices are supported.
* UFI subclass(SubClassCode value is 04h) devices are unsupported.
¾CBI Transport devices such as USB FDDs are unsupported, even if they are Mass Storage Class
devices. Likewise, devices manufactured before the implementation of Mass Storage Class standards
and not conforming to those standards will not be supported.
•Non-Mass Storage Class devices are not supported.
Note the following precautions regarding operations.
•These functions are disabled if the LSI switches to Sleep mode while functions are underway. Operation
will resume on recovery from Sleep mode in the state immediately preceding Sleep mode.

Control PC
Fig. 2-1 Typical hardware configuration
The blocks shown in Fig. 2-1 are as follows:
•Board containing S1R72U16
¾Corresponds to the product (system) board. These functions are controlled by the control PC.
•Control PC
¾PC used to control these functions via terminal software using the RS-232 interface function.
•USB device
¾A USB device such as USB memory, HDD, CD, DVD, or MO drive. Connect when using the
IDE-USB bridge. Not required if only checking (initializing) the connection between the LSI and main
CPU.
Table 2-1 shows RS-232 and terminal software settings.

3. Operating Procedures
3. Operating Procedures
Control these functions as shown in Fig. 3-1.
Fig. 3-1 History display function operating procedures
These functions are enabled once the PLL_Locked pin (Port13) switches to High. Confirm that the signal is
at High before starting these functions (i.e., before entering “menu”).
Consider the following possible causes if the PLL_Locked pin (Port13) fails to switch to High.
•The specified power supply is not provided to the LSI.
•The LSI reset pin (XRESET) is still at Low.
S1R72U16 Development EPSON 3
Support Manual (Rev.2.00)

3. Operating Procedures
•The clock is not oscillating correctly.
Consider the following possible causes if transfer is not possible even though the PLL_Locked pin (Port13)
has switched to High.
•The CLKSEL pin setting does not match the clock frequency.
•The RS-232 cable (cross/straight) used is incorrect for the circuit board wiring.
•The terminal software settings differ from those described in Table 2-1.
3.1 Key Input Specifications
The key input specifications are as follows:
•The Enter key confirms the string entered.
•Only single-byte alphanumeric characters can be entered. Double-byte characters are invalid.
•Input is not case-sensitive.
3.2 Main Menu
Start these functions by entering “menu” via the PC terminal software. This will display the items
shown in Table 3-1.
Table 3-1 Main menu list
Key Input Item Summary
1 USB analog test Allows switching to Test mode.
2 Diagnostic Starts the history display function.
q Quit Quits the function.
3.2.1 USB Analog Test
When key input “1” is received, then the operation menu is displayed and to allow
switching to Test mode. For detailed information, refer to S1R72U16 Embedded Host
Compliance Guide.
3.2.2 Diagnostic
When key input “2” is received, then the operation menu is displayed and to start the
history display function. For detailed information, refer to “3.3 History Display Function
Menu”.
3.2.3 Quit
When key input “q” is received, then this quits the function. The function will be
unavailable until the “menu” is invoked once again.

3. Operating Procedures
3.3 History Display Function Menu
Table 3-2 shows the items that can be used with the history display function.
Table 3-2 History display function menu list
Key Input Item Summary
1 Show diagnostic data Displays the history data.
2 Clear historical data Clears the history data recorded.
q Quit Quits the history display function.
3.3.1 Show Diagnostic Data
When key input “1” is received, the history data is displayed. Then the menu shown in
Table 3-2. History data includes both USB and IDE related data and is displayed in
chronological order, starting with the oldest. Up to 63 messages can be displayed. Tables
4-1 and 4-2 show the display details.
3.3.2 Clear Historical Data
When key input “2” is received, recorded history data is all cleared. Then the menu shown
in Table 3-2. History data recording resumes after the previous data has been cleared.
3.3.3 Quit
When key input “q” is received, then this quits the history display function and returns to
the main menu.
