Port 2 Data Register (P2DR)
P2DR is an 8-bit readable/writable register that stores output data for the port 2 pins (P27 to P20).
If a port 2 read is performed while P2DDR bits are set to 1, the P2DR values are read directly,
regardless of the actual pin states. If a port 2 read is performed while P2DDR bits are cleared to 0,
the pin states are read.
P2DR is initialized to H'00 by a reset and in hardware standby mode. It retains its prior state in
software standby mode.
Port 2 MOS Pull-Up Control Register (P2PCR)
P2PCR is an 8-bit readable/writable register that controls the port 2 built-in MOS input pull-ups
on a bit-by-bit basis.
In modes 2 and 3, the MOS input pull-up is turned on when a P2PCR bit is set to 1 while the
corresponding P2DDR bit is cleared to 0 (input port setting).
P2PCR is initialized to H'00 by a reset and in hardware standby mode. It retains its prior state in
software standby mode.

Modes 2 and 3 (EXPE = 0)
The corresponding port 2 pins are output ports or PWM outputs when P2DDR bits are set to 1,
and input ports when cleared to 0.
P27 can be used as an on-chip supporting module output pin regardless of the P27DDR setting.
