Description
In modes 4 to 6, if a pin is in the input state in
accordance with the settings in the LCD driver’s LPCR
and in DDR, setting the corresponding PBPCR 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 the LCD driver’s LPCR and in DDR,
setting the corresponding PBPCR 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 PBODR bit makes the corresponding
port A pin an NMOS open-drain output, while clearing
the bit to 0 makes the pin a CMOS output. Do not set
this register to 1 when the pins are used as the LCD
driver pins.
