Port data register 2
Port control register 2
Port Data Register 2 (PDR2)
Note:
PDR2 is an 8-bit register that stores data for port 2 pins P2
bits are set to 1, the values stored in PDR2 are read, regardless of the actual pin states. If port 2 is
read while PCR2 bits are cleared to 0, the pin states are read.
Upon reset, PDR2 is initialized to H'00.
