PGPIN is at the same address as PGDDR. Writing is to PGDDR and the port G settings will
change unless the given byte represents the current settings.
Port G Nch-OD Control Register (PGNOCR)
PGNOCR is an 8-bit read/write register, the individual bits of which specify the output driver type
for pins on port G which are configured as outputs.
Setting a PENOCR or PFNOCR bit to 1 disables the P-channel driver for the corresponding pin on
port G. 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 look like CMOS when the bit is cleared
to 0 and N-channel open-drain when it is set to 1.
PGNOCR is initialized to H'00 by a reset and in hardware standby mode. It retains its prior state in
software standby mode.
