Port 1 Data Register (P1DR)
P1DR is an 8-bit readable/writable register that stores output data for the port 1 pins (P17 to P10).
If a port 1 read is performed while P1DDR bits are set to 1, the P1DR values are read directly,
regardless of the actual pin states. If a port 1 read is performed while P1DDR bits are cleared to 0,
the pin states are read.
P1DR is initialized to H'00 by a reset and in hardware standby mode. It retains its prior state in
software standby mode.
Port 1 MOS Pull-Up Control Register (P1PCR)
P1PCR is an 8-bit readable/writable register that controls the port 1 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 P1PCR bit is set to 1 while the
corresponding P1DDR bit is cleared to 0 (input port setting).
P1PCR is initialized to H'00 by a reset and in hardware standby mode. It retains its prior state in
software standby mode.
