PFCR is an 8-bit read/write register that controls the address output in on-chip ROM-enabled
expansion mode.
PFCR is initialized to H'0D/H'00 by a reset and in hardware standby mode. It retains its previous
state in software standby mode.
Bits 7 to 4—Reserved: Only 0 should be written to these bits.
Bits 3 to 0—Address Output Enable 3 to 0 (AE3 to AE0): These bits select enabling or
disabling of address outputs A8 to A23 in on-chip ROM-disabled expansion mode and on-chip
ROM-enabled expansion mode. When a pin is enabled for address output, the address is output
regardless of the corresponding DDR setting. When a pin is disabled for address output, it
becomes an output port when the corresponding DDR bit is set to 1.
