Port C MOS Pull-Up Control Register (PCPCR)
PCPCR is an 8-bit readable/writable register that controls the MOS input pull-up function
incorporated into port C on an individual bit basis.
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.
PCPCR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state by
a manual reset or in software standby mode.
Port C Open Drain Control Register (PCODR)
Bit
Initial value
Read/Write
PCODR is an 8-bit readable/writable register and controls PMOS On/Off of each pin (PC7 to
PC0) of port C.
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.
PCODR is initialized to H'00 in reset mode or hardware standby mode. PCODR retains the last
state in software standby mode.
