Port Data Register 3 (PDR3)
PDR3 is an 8-bit register that stores data for port 3 pins P3
bits are set to 1, the values stored in PDR3 are read, regardless of the actual pin states. If port 3 is
read while PCR3 bits are cleared to 0, the pin states are read.
Upon reset, PDR3 is initialized to H'00.
Port Control Register 3 (PCR3)
PCR3 is an 8-bit register for controlling whether each of the port 3 pins P3
input pin or output pin. Setting a PCR3 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 PCR3 and in PDR3 are valid only
when the corresponding pin is designated in PMR3 as a general I/O pin.
Upon reset, PCR3 is initialized to H'00.
PCR3 is a write-only register. All bits are read as 1.
Port Pull-Up Control Register 3 (PUCR3)
PUCR3 bits control the on/off state of pin P3
0, setting the corresponding PUCR3 bit to 1 turns on the MOS pull-up for the corresponding pin,
while clearing the bit to 0 turns off the MOS pull-up.
Upon reset, PUCR3 is initialized to H'00.
