8.14.3
The port C and port D pins have only one special function.
8.14.4
Port C and port D have a built-in MOS input pull-up function that can be controlled by software.
This MOS input pull-up function can be switched on or off on a bit-by-bit basis.
When a PCDDR or PDDDR bit is cleared to 0, setting the corresponding PCODR or PDODR bit
to 1 will turn on the MOS input pull-up for that pin.
The MOS input pull-up function is off after a reset and in hardware standby mode. The prior state
is retained when in software standby mode.
Table 8.28 is a summary of the MOS input pull-up states.
Table 8.28 MOS Input Pull-Up States (Port C and port D)
Legend:
Off:
On/Off: On when PCDDR = 0 and PCODR = 1 (PDDDR = 0 and PDODR = 1); otherwise off.
Mode
1 to 3
MOS input pull-up is always off.
