Section 9 I/O Ports
In modes 5 to 7, P2DDR is a write-only register. Its value cannot be read. All bits return 1 when
read.
P2DDR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode
it retains its previous setting. If a P2DDR bit is set to 1, the corresponding pin maintains its output
state in software standby mode.
Port 2 Data Register (P2DR)
P2DR is an 8-bit readable/writable register that stores output data for pins P2
in P2DDR is set to 1, if port 2 is read the value of the corresponding P2DR bit is returned. When a
bit in P2DDR is cleared to 0, if port 2 is read the corresponding pin level is read.

Port 2 Input Pull-Up MOS Control Register (P2PCR)
P2PCR is an 8-bit readable/writable register that controls the MOS input pull-up transistors in port
2.
