Description
In modes 4 to 6, if a pin is in the input state in
accordance with the settings in PFCR, in LPCR, and in
DDR, setting the corresponding PAPCR bit to 1 turns
on the MOS input pull-up for that pin.
In mode 7, if a pin is in the input state in accordance
with the settings in LPCR and DDR, setting the
corresponding PAPCR bit to 1 turns on the MOS input
pull-up for that pin.
Description
When pins are not address and LCD outputs in
accordance with the setting of bits AE3 to AE0 in
PFCR, setting a PAODR bit makes the corresponding
port A pin an NMOS open-drain output, while clearing
the bit to 0 makes the pin a CMOS output.
