8.3.4
Port 2 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 2 and 3, and can be specified as on or off on a bit-by-
bit basis.
When a P2DDR bit is cleared to 0 in mode 2 or 3, setting the corresponding P2PCR bit to 1 turns
on the MOS input pull-up for that pin.
The MOS input pull-up function is in the off state after a reset and in hardware standby mode. The
prior state is retained in software standby mode.
Table 8.6 summarizes the MOS input pull-up states.
