Port data register 5 (PDR5) stores the data for the pins P53 to P50 of port 5. When PCR5 is 1
(output), the PDR5 values are directly read if port 5 is read. Accordingly, the pin states are not
affected. When PCR5 is 0 (input), the pin states are read if port 5 is read.
PDR5 is an 8-bit read/write enable register. When reset, PDR5 is initialized to H'F0.
Bits 7 to 4 are reserved bits.
