SECTION 1
INTRODUCTION
This document is the MPC821FADS daughterboard operation guide. The daughterboard
encompasses the MPC821 device along with some necessary logic that must be in close
proximity to the MPC821 and peripherals. These peripherals are dedicated to the MPC821,
but are not necessarily required for any other member of the MPC8xx Family. The
daughterboard has two sets of matching connectors—one set on the print side (on the
bottom of the board) and one on the component side (on the top of the board). Those on the
print side connect to a matching set found on the MPC8xxFADS, while those on the
componentside areto servehardware expansionvia adedicated adaptor.Also aset oflogic
analyzer connectors is featured matching the new high-density HP16500 logic analyzer
adaptors to provide fast connection to a logic analyzer while saving board space and
reducing EMI.

MOTOROLA MPC821FADS-DB USER’S MANUAL 2-1
SECTION 2
INSTALLATION
This section contains information about preparing, configuring, and installing the
MPC821FADS daughterboard. When you receive your daughterboard it should already be
connected to the MPC8xxFADS motherboard. You should unpack the shipping carton and
verify the contents against the packing list. If the contents were damaged during shipping,
call your local Motorola sales office, explain the problem, and you should receive another
package. If the contents are undamaged, save the packing slip and start configuring the
board for your design.
2.1 CONFIGURING THE BOARD
Before you configure the MPC821FADS daughterboard, you may have to change the
jumpers settings before you can install the board into your system. Since they are factory
set and tested, they may not be set correctly for your particular configuration. Figure 2-1
illustrates the location of these jumpers, LEDs, and connectors on the board. The
MPC821FADS daughterboard settings contain the following parameters that you can
change for your specific configuration:
• Clock generator
• Power-on reset source
• MPC821 keep-alive power source
• MPC821 internal logic supply source
Caution: Avoid touching the integrated circuitry of the board with your hands since static
discharge can damage circuits.

2.1.1 Replacing the Clock Generator
When replacing the clock generator (U1), all you need to know is that there are two supply
levels. A 5V supply is available at Pin 14 and a 3.3V supply is available at Pin 11. To replace
it, just pop it out of the socket. Figure 2-2 illustrates that a 5V oscillator (with 3.3V output
only) can be used with a 14-pin form-factor, while 3.3V oscillators can be used with an 8-pin
form-factor.
Inserting a 14-pin form-factor 3.3V clock generator into U1 could cause permanent damage
to your device. Since the MPC821 clock input is not 5V-tolerant, any clock generator
inserted into U1 must have a 3.3V-compatible output. If you insert a 5V output clock
generator into U1, you could cause permanent damage to the MPC821 microprocessor.

2.1.2 Selecting the Power-On Reset Source
The functionality of the power-on reset logic changes with each revision of the MPC821. For
your purposes, this means that you may need to select a different source to generate a
power-on reset. To select your power-on reset source, you need to set J1 on the
MPC821FADS daughterboard. When the J1 jumper is between positions 1 and 2, a
power-on reset is generated by the keep-alive power rail (KAPWR). For example, when
KAPWRgoes below2.005V, a power-onreset isgenerated. When theJ1 jumperisbetween
positions 2 and 3, a power-on reset is generated from the main 3.3V power rail. In other
words, when the 3.3V power rail gets below 2.805V, a power-on reset is generated.
2.1.3 Selecting the Keep-Alive Power Source
The J2 jumper is used to select the keep-alive power source. When the J2 jumper is
between positions 1 and 2, the keep-alive power is fed from the main 3.3V bus. When you
need to connect an external power source (such as a battery) to the keep-alive power rail,
it should be connected between positions 2 (the positive pole) and 3 (GND).

SECTION 3
OPERATION
This section contains the necessary information you need to operate the MPC821FADS
daughterboard.
3.1 INDICATORS
The MPC821FADS daughterboard does not have any switches, but it has five indicators.
3.1.1 Ground Bridges
There are four ground (GND) bridges on the MPC821FADS daughterboard. They can be
used to assist you with easy ground access points for general measurements and a logic
analyzer connection.
3.1.2 3.3V Indicator
The yellow 3.3V light (LD1) indicates that the 3.3V power bus is receiving power from the
MPC8xxFADS motherboard.
3.1.3 Memory Map
The memory map is the same on all daughterboards. See Section 3.3 Memory Map of the
MPC8xxFADS User’s Manual for more information.
3.1.4 Programming the MPC821 Registers
To program the MPC821 registers, see Section 3.1.7 Programming the MPC821
Registers of the MPC8xxFADS User’s Manual.
Warning: The onboard GND bridges physically resemble the J4 jumper and you should
take care not to mistake it for a GND jumper. Doing so could cause permanent
damage to your MPC821FADS daughterboard or MPC8xxFADS
motherboard. When you are connecting to a GND bridge, use only insulated
GND clips to keep from damaging the board.

SECTION 4
FUNCTIONALITY
This section describes the main functions of the MPC821FADS daughterboard.
• Reset
• Interrupts
• Clock generator
• LCD panel support
• Board control and status registers
4.1 RESET
There are three sources of reset for the MPC821 microprocessor:
• Power-on reset
• Hard reset
• Soft reset
4.1.1 Power-On Reset
Onthe MPC821FADS daughterboard,a power-on resetcan be generated froma keep-alive
powerbus or a mainpowerbus. The J1 jumper isused to select one ofthese sources. When
you select the keep-alive power source, a dedicated voltage detector made by Seiko
(S-8051HN-CD-X), which has a detection voltage range of 1.795–2.005V, generates the
power-on reset. During a keep-alive power-on, or when there is a voltage drop of that input
into the above range, a power-on reset is generated (the PORESET input of the MPC821 is
asserted for approximately 4 seconds).
When you select the main power source, a dedicated voltage detector made by Seiko
(S-8052ANY-NH-X), with a detection voltage range of 2.595–2.805V, generates the
power-on reset. During a main 3.3V bus power-on, or when there is a voltage drop of that
input into the above range, a power-on reset is generated (the PORESET input of the
MPC821is asserted for approximately 4 seconds). The main power-onresetalso generates
a power-on reset to all logic on the motherboard.
Thepower-onresetconfigurationis read by the MPC821 when PORESET is asserted to the
MPC821. See Section 4.1.6.1 Power-On Reset Configuration of the
MPC8xxFADS
User’s Manual
for more information.

4.1.2 Hard Reset
A hard reset is generated from four possible sources:
• A main power-on reset
• A manual hard reset generated on the motherboard
• A debug port hard reset
• An internal source of the MPC821
When the open-drain HRESET signal is asserted, hard reset configuration data is driven on
the data bus by the motherboard logic. See Section 4.1.6.2 Hard Reset Configuration of
the
MPC8xxFADS User’s Manual for details.
4.1.3 Soft Reset
A soft reset is generated from three possible sources:
• The debug port controller on the motherboard
• A manual soft reset generated on the motherboard
• An internal source of the MPC821
The motherboard logic makes a soft reset configuration available to the MPC821 when a
soft reset is generated to the MPC821. See Section 4.1.6.2 Soft Reset Configuration of
the
MPC8xxFADS User’s Manual for details.
4.2 INTERRUPTS
The only external interrupt that is applied to the MPC821 via its interrupt controller is the
abort (NMI) interrupt, which is generated by a push-button and logic that resides on the
motherboard.
4.3 CLOCK GENERATOR
Although most of the clock generator logic is found on the daughterboard, it is explained in
detail in the motherboard manual since it is common to all daughterboards. See Section 4.3
Clock Generator of the
MPC8xxFADS User’s Manual for more information.
4.4 LCD PANEL SUPPORT
AdedicatedLCDconnectorisprovidedwith yourboardto allowconnectionto anLCDpanel.
This connector contains the MPC821 Port D pins. The LCD connector is a superset of the
LCD connector on the MPC821FADS board, which makes it easy to move tools between
the two boards and to connect the additional color bits.
To make connecting even easier, there are 5V supply pins available on the LCD connector.
For a description of these signals, refer to Table 5-8 in Section 5 Signal Descriptions .
