PEPIN and PFPIN are at the same addresses as PEDDR and PFDDR, respectively. Writing is to
PEDDR or PFDDR and the port E or port F settings will change unless the given byte represents
the current setting.
Port E and port F Nch-OD Control Registers (PENOCR, PFNOCR)
PENOCR and PFNOCR are 8-bit read/write registers, the individual bits of which specify the
output driver type for pins on ports E and F which are configured as outputs.
Setting a PENOCR or PFNOCR bit to 1 disables the P-channel driver for the corresponding pin on
port E or port F. Clearing the bit to 0 enables the P-channel driver for the pin. Although the P-
channel drivers are always connected, the output driver type will be CMOS when the bit is cleared
to 0 and N-channel open-drain when it is set to 1.
PENOCR and PFNOCR are initialized to H'00 by a reset and in hardware standby mode. They
retain their prior states in software standby mode.
