Port 4 Data Register (P4DR)
P4DR is an 8-bit register that stores data for pins P4
4 is read, the value in P4DR is obtained directly, regardless of the actual pin state. When a P4DDR
bit is cleared to 0, if port 4 is read the pin state is obtained. This also applies to pins used by on-
chip supporting modules.
P4DR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its existing values.
