Section 16 Pin Function Controller (PFC)
16.3.7
The port D IO register (PDIOR) is a 16-bit readable/writable register that selects the input/output
direction of the 16 pins in port D. Bits PD15IOR to PD0IOR correspond to pins PD15/D15 to
PD0/D0. PDIOR is enabled when port D pins function as general input/output pins (PD15 to
PD0), and disabled otherwise.
When port D pins function as PD15 to PD0, a pin becomes an output when the corresponding bit
in PDIOR is set to 1, and an input when the bit is cleared to 0.
PDIOR is initialized to H'0000 by a power-on reset (excluding a WDT power-on reset), and in
hardware standby wode. It is not initialized in software standby mode or sleep mode.
16.3.8
The port D control register (PDCR) is a 16-bit readable/writable register that selects the functions
of the 16 multiplex pins in port D. PDCR settings are not valid in all operating modes.
1. Expanded mode with on-chip ROM disabled (area 0: 8-bit bus)
2. Expanded mode with on-chip ROM disabled (area 0: 16-bit bus)
3. Expanded mode with on-chip ROM enabled
4. Single-chip mode
