MOS Input Pull-Up Function
Port C has a built-in MOS input pull-up function that can be controlled by software. This MOS
input pull-up function can be used in modes 6 and 7, and can be specified as on or off on an
individual bit basis.
In modes 6 and 7, when PCPCR is set to 1 in the input state by setting of DACR and PCDDR, the
MOS input pull-up is set to ON.
The MOS input pull-up function is in the off state after a power-on reset, and in hardware standby
mode. The prior state is retained by a manual reset or in software standby mode.
Table 10-15 summarizes the MOS input pull-up states.
