14.5.1 Port C Data Register
MC68HC908MR8 — Rev 4.1
Freescale Semiconductor
NOTE:
Port C bit 1 is not used on the 28-pin packages. For that reason, a
pull-down resistor is connected to V
FAULT4.
PORTC has the capability of being used as an output port. When either
pin of PORTC is set as an output, by setting its respective PORTC data
direction register bit, the respective fault pin logic is disconnected from
that pin and the fault input will be defaulted to normal non-fault condition
to facilitate the use of PORTC as an output pin and not interfere with the
PWM generator. To regain the fault capability for the respective fault
input pin, clear the PORTC data direction register bit for that pin.
The port C data register (PTC) contains a data latch for each of the two
port C pins.

These read/write bits are software programmable. Data direction of
each port C pin is under the control of the corresponding bit in data
direction register C. Reset has no effect on port C data.
