9.2.1

Port Control Register 2 (PCR2)

PCR2 selects inputs/outputs in bit units for pins to be used as general I/O ports of port 2.

When each of the port 2 pins P24 to P20 functions as a

general I/O port, setting a PCR2 bit to 1 makes the

corresponding pin an output port, while clearing the bit

to 0 makes the pin an input port.

Port Data Register 2 (PDR2)

PDR2 is a general I/O port data register of port 2.

PDR2 stores output data for port 2 pins.

If PDR2 is read while PCR2 bits are set to 1, the values

stored in PDR2 are read. If PDR2 is read while PCR2

bits are cleared to 0, the pin states are read regardless

of the value stored in PDR2.
