12.8 Port F
Port F is an 8-bit special-function port that shares four of its pins with the timer interface (TIM2) module.
12.8.1 Port F Data Register
The port F data register (PTF) contains a data latch for each of the eight port F pins.
PTF7–PTF0 — Port F Data Bits
Freescale Semiconductor
1. X = Don’t care
2. Hi-Z = High impedance
3. Writing affects data register, but does not affect input.
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 port F data.
