Rev. 1.1
Address:
When DDREx is a logic 1, reading address $0008 reads the PTEx data
latch. When DDREx is a logic 0, reading address $0008 reads the
voltage level on the pin. The data latch can always be written, regardless
of the state of its data direction bit.
Table 17-6
Port F is an 8-bit special function port that shares six of its pins with the
timer interface modules (TIMA and TIMB).
The port F data register contains a data latch for each of the eight port F
pins.
Notes:
Reset:
1. X = don’t care.
2. Hi-Z = high impedance.
3. Writing affects data register, but does not affect the input.
