21.1.7 Port D I/O Registers L, H (PDIORL, PDIORH)
PDIORL and PDIORH are 16-bit readable/writable registers that are used to set the pins on port D
as inputs or outputs. Bits PD31IOR to PD0IOR correspond to pins PD31 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 (PD15 to PD0), and the TIOC
pin is functioning as inputs/outputs of MTU2S. In other states, PDIORL is disabled. PDIORH is
enabled when the port D pins are functioning as general-purpose inputs/outputs (PD31 to PD16),
and the TIOC pin is functioning as inputs/outputs of MTU2S. In other states, PDIORH is disabled.
A given pin on port D will be an output pin if the corresponding bit in PDIORH or PDIORL is set
to 1, and an input pin if the bit is cleared to 0. However, PDIORH is disabled in SH7083/SH7084.
The initial values of PDIORL and PDIORH are H'0000, respectively.
