1. Port data register 9 (PDR9)
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'F0.
2. Port control register 9 (PCR9)
PCR9 is an 8-bit register for controlling whether each of the port 9 pins P9
input pin or output pin. 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'F0.
PCR9 is a write-only register, which is always read as all 1s.
