Table 8.29 is a summary of the port E and port F registers.
Table 8.29 Port E and port F Registers
Notes: 1. Lower 16 bits of the address.
Port E and port F Data Direction Registers (PEDDR, PFDDR)
PEDDR and PFDDR are 8-bit write-only registers, the individual bits of which select input or
output for the pins of port E and port F. PEDDR and PFDDR are at the same addresses as PEPIN
and PFPIN, respectively, and if read, will return the port E and port F pin states.
Setting a PEDDR or PFDDR bit to 1 makes the corresponding pin on port E or port F an output
pin, while clearing the bit to 0 makes the pin an input pin.
