General Description
Pin Assignments
Port H I/O pins
(PTH1/KBD4ÐPTH0/
KBD3)
PTH1/KBD4–PTH0/KBD3 are general-purpose bidirectional I/O pins
with Key Wakeup feature. See Keyboard Module (KB) on page 319
and I/O Ports on page 327.
CAN transmit pin
(CANTx)
CANTx is the digital output from the msCAN module. See msCAN08
Controller (msCAN08) on page 351.
CAN receive pin
(CANRx)
CANRx is the digital input to the msCAN module. See msCAN08
Controller (msCAN08) on page 373
Power supply
pins(E_VDD3/E_VDD1
and E_VSS4/E_VSS1)
The E_VDD and E_VSS pins are for the sole use of the I/O pins. This will help
reduce the effect of the noise induced into the V_SS power supply.
External data pins EDB7–EDB0 are the bidirectional data lines for connection to external
(EDB7ÐEDB0)
peripherals.
External address
EAB15–EAB0 are the address lines for connection to external
pIns (EAB15ÐEAB0) peripherals. See EBI.
Write control pin
(WEB)
WEB is the write control signal for external peripherals. See EBI.
Read control pin
(REB)
REB is the read control signal for external peripherals. See EBI.
WAIT states clock
pin (WSCLK)
WSCLK is the External WAIT State control signal. See EBI.
External
chip-select pins
(CS1,CS0)
9-gen
MOTOROLA
CS1 and CS0 are the chip-select lines for connection to external
peripherals. See EBI. The external pins are summarized in Table 1 and
the clock sources are shown in Table 3.
