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, which is always read as all 1s.
Port Pull-Up Control Register 3 (PUCR3)
Note:
PUCR3 controls whether the MOS pull-up of each of the port 3 pins P3
a PCR3 bit is cleared to 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.
