The port D I/O register L (PDIORL) is a 16-bit read/write register that selects input or output for
the sixteen port D pins. Bits PD15IOR to PD0IOR correspond to the PD15/D15 pin to PD0/D0
pin. PDIORL is enabled when the port D pins function as general input/outputs (PD15 to PD0).
For other functions, it is disabled.
For port D pin functions PD15 to PD0, a given pin in port D is an output pin if its corresponding
PDIORL bit is set to 1, and an input pin if the bit is cleared to 0.
PDIORL is initialized to H'0000 by external power-on reset; however, it is not initialized for reset
by WDT, standby mode, or sleep mode, so the previous data is maintained.
The settings in this register are functional only in the SH7016 and SH7017. In the SH7014, there
are no pins corresponding to this register, and it should not be read or written to.
