Port Data Register 4 (PDR4)
PDR4 is an 8-bit register that stores data for port 4 pins P4
bits are set to 1, the values stored in PDR4 are read, regardless of the actual pin states. If port 4 is
read while PCR4 bits are cleared to 0, the pin states are read.
Upon reset, PDR4 is initialized to H'F8.
Port Control Register 4 (PCR4)
PCR4 controls whether each of the port 4 pins P4
Setting a PCR4 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 PCR4 and in PDR4 are valid only when the
corresponding pin is designated in SCR3 as a general I/O pin.
Upon reset, PCR4 is initialized to H'F8.
PCR4 is a write-only register. All bits are read as 1.
