22. Pin Function Controller (PFC)
Port H pins D0 to D7 function as data input/output pins, and PHCR settings are invalid.
2. Expanded mode with on-chip ROM disabled (area 0: 16-bit bus)
Port H pins function as data input/output pins, and PHCR settings are invalid.
3. Expanded mode with on-chip ROM enabled
Port H pins are multiplexed as data input/output pins and general input/output pins. PHCR settings are valid.
4. Single-chip mode
Port H pins function as general input/output pins, and PHCR settings are invalid.
PHCR is initialized to H'0000 by a power-on reset (excluding a WDT power-on reset), in hardware standby mode, and in
software standby mode. It is not initialized in sleep mode.
