Address:
Port F is a 7-bit special function port that shares four of its pins with the
timer interface module (TIMA-6) and two of its pins with the timer
interface module (TIMB) on the 68HC908AZ32A. Note that PTF4, PTF5
and PTF6 are only available on 64-pin package options.
The port F data register contains a data latch for each of the seven port
F pins.
PTF[6:0] — Port F Data Bits

Freescale Semiconductor, Inc.
These read/write bits are software programmable. Data direction of
each port F pin is under the control of the corresponding bit in data
direction register F. Reset has no effect on PTF[6:0].
The PTF3/TCH5–PTF0/TCH2 pins are the TIM input capture/output
compare pins. The edge/level select bits, ELSxB:ELSxA, determine
whether the PTF3/TCH5–PTF0/TCH2 pins are timer channel I/O pins
or general-purpose I/O pins. (See
