18.1.5 Port D I/O Register L (PDIORL)
PDIORL is a 16-bit readable/writable register that is used to set the pins on port D as inputs or
outputs. Bits PD10IOR to PD0IOR correspond to pins PD10 to PD0 (names of multiplexed pins
are here given as port names and pin numbers alone). PDIORL is enabled when the port D pins are
functioning as general-purpose inputs/outputs (PD10 to PD0). In other states, PDIORL is disabled.
A given pin on port D will be an output pin if the corresponding bit in PDIORL is set to 1, and an
input pin if the bit is cleared to 0.
However, bits 15 to 11 in PDIORL are disabled.
The initial value of PDIORL is H'0000.
