Description
In modes 6 and 7, if PCPCR is set to 1 when the port is
in the input state in accordance with the settings of the
LCD driver LPCR and PCDDR, the MOS input pull-up is
set to ON.
Description
If PCODR is set to 1 by setting AE3 to AE0 in PFCR in
mode other than address output mode, port C pins
function as NMOS open drain outputs and when the
setting is cleared to 0, the pins function as CMOS
outputs.
Do not set PCODR to 1 if the pins are being used for
LCD driver output.
