I/O Ports
20.8 Port F
Port F is a 7-bit special function port that shares four of its pins with the
timer interface module (TIMA) and two of its pins with the timer interface
module (TIMB)).
20.8.1 Port F Data Register (PTF)
The port F data register contains a data latch for each of the seven port
F pins.

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/TACH5–PTF0/TACH2 pins are the TIM input
capture/output compare pins. The edge/level select bits,
ELSxB:ELSxA, determine whether the PTF3/TACH5–PTF0/TACH2
pins are timer channel I/O pins or general-purpose I/O pins.
