Port 2 Data Register (P2DR)
P2DR is an 8-bit register that stores data for pins P2
2 is read, the value in P2DR is obtained directly, regardless of the actual pin state. When a P2DDR
bit is cleared to 0, if port 2 is read the pin state is obtained.
P2DR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its existing values.
Port 2 Input Pull-Up Control Register (P2PCR)
P2PCR is an 8-bit readable/writable register that controls the input pull-up transistors in port 2. If
a P2DDR bit is cleared to 0 (designating input) and the corresponding P2PCR bit is set to 1, the
input pull-up transistor is turned on.
P2PCR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its existing values.
