Section 9 I/O Ports
9.8.4
Port C has an on-chip 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 PCDDR, the MOS input
pull-up is set to ON.
The MOS input pull-up function is in the off state after a reset, and in hardware standby mode.
The prior state is retained by a manual reset or in software standby mode.
Table 9-14 summarizes the MOS input pull-up states.
