Port C MOS Input Pull-Up States
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 4 and 7. MOS input pull-up can be specified as on or
off on a bit-by-bit basis.
In modes 4 and 7, when a PCDDR bit is cleared to 0, setting the corresponding PCPCR bit to 1
turns on the MOS input pull-up for that pin.
Table 9.4 summarizes the MOS input pull-up states.
