Port F Register (PORTF)
PORTF is an 8-bit read-only register that shows the pin states. Writing of output data for the port
F pins (PF
If a port F read is performed while PFDDR bits are set to 1, the PFDR values are read. If a port F
read is performed while PFDDR bits are cleared to 0, the pin states are read.
After a power-on reset and in hardware standby mode, PORTF contents are determined by the pin
states, as PFDDR and PFDR are initialized. PORTF retains its prior state after a manual reset, and
in software standby mode.
