7.2.6
PFCR is an 8-bit readable/writable register that performs address output control in external
expanded 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 and 6—Reserved: Only 0 should be written to these bits.
Bit 5—BUZZ Output Enable (BUZZE): Enables or disables BUZZ output from the PF1 pin. For
details, see section 12.2.4, Pin Function Control Register (PFCR).
Bit 4—Reserved: Only 0 should be written to this bit.
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 ROMless expanded mode and modes with ROM. When
a pin is enabled for address output, the address is output regardless of the corresponding DDR
