Section 8 I/O Ports
PDR9 is an 8-bit register that stores data for port 9 pins P9
bits are set to 1, the values stored in PDR9 are read, regardless of the actual pin states. If port 9 is
read while PCR9 bits are cleared to 0, the pin states are read.
Upon reset, PDR9 is initialized to H'C0.
Port Control Register 9 (PCR9)
PCR9 controls whether each of the port 9 pins P9
Setting a PCR9 bit to 1 makes the corresponding pin an output pin, while clearing the bit to 0
makes the pin an input pin.
Upon reset, PCR9 is initialized to H'C0.
PCR9 is a write-only register, which is always reads as all 1.
