PTF[6:0] — Port F Data Bits
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].
TACH[5:2] — Timer A Channel I/O Bits
The PTF3–PTF0/TACH2 pins are the TIM input capture/output
compare pins. The edge/level select bits, ELSxB:ELSxA, determine
whether the PTF3–PTF0/TACH2 pins are timer channel I/O pins or
general-purpose I/O pins. (See TIMA Status and Control Register
on page 380).
