Port 2 has an on-chip input pull-up MOS function that can be controlled by software. This input
pull-up MOS function can be specified as on or off on a bit-by-bit basis.
Table 8.3 summarizes the input pull-up MOS states.

The pin function is switched as shown below according to the combination of the OEm bit in
PWOERB of PWM, the P2nDDR bit, and operating mode.
Input pull-up MOS is always off.
