Freescale Semiconductor, Inc.
General Description
PA0–PA5
pins that are ORed to create the IRQ signal. For more information, refer
to 4.6 External Interrupts.
1.10 PA0–PA5
These six I/O lines comprise port A, a general-purpose bidirectional I/O
port. This port also has four pins which have keyboard interrupt
capability. All six of these pins have high current source and sink
capability.
All of these pins have software programmable pulldowns which can be
disabled by the SWPDI bit in the MOR.
1.11 PB0–PB7
These eight I/O lines comprise port B, a general-purpose bidirectional
I/O port. This port is also shared with the 16-bit programmable timer
input capture and output compare functions, with the two voltage
comparators in the analog subsystem, and with the simple serial
interface (SIOP).
The outputs of voltage comparator 1 can directly drive the PB4 pin; and
the PB4 pin has high current source and sink capability.
All of these pins have software programmable pulldowns which can be
disabled by the SWPDI bit in the MOR.
1.12 PC0–PC7 (MC68HC705JP7)
These eight I/O lines comprise port C, a general-purpose bidirectional
I/O port. This port is only available on the 28-pin MC68HC705JP7. All
eight of these pins have high current source and sink capability.
All of these pins have software programmable pulldowns which can be
disabled by the SWPDI bit in the MOR.
