Port F Data Register (PFDR)
PFDR is an 8-bit readable/writable register that stores output data for the port F pins (PF
PFDR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state in
software standby mode.
Port F Register (PORTF)
Note: * Determined by state of pins PF
PORTF is an 8-bit read-only register that shows the pin states. It cannot be written to. 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 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 in software standby mode.
