Port Data Register 2 (PDR2)
PDR2 is an 8-bit register that stores data for pins P2
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.
Port Control Register 2 (PCR2)
PCR2 is an 8-bit register for controlling whether each of the port 2 pins P2
input pin or output pin. Setting a PCR2 bit to 1 makes the corresponding pin an output pin, while
clearing the bit to 0 makes the pin an input pin. The settings in PCR2 and in PDR2 are valid only
when the corresponding pin is designated in PMR2 as a general I/O pin.
Upon reset, PCR2 is initialized to H'00.
PCR2 is a write-only register. All bits are read as 1.
Port Mode Register 2 (PMR2)
PMR2 is an 8-bit read/write register, controlling the selection of pin functions for pins P2
P2
TMIG input noise canceller.
Upon reset, PMR2 is initialized to H'C0.
