6.3.6
PFCR performs address output control in external extended mode. When using the USB with the
emulator (E6000), enable the A8 and A9 output by setting AE3 to AE0 to 0010.
Note: * In modes 4 and 5, initial value of each bit is 1. In modes 6 and 7, initial value of each bit is 0.

The write value should always be 0.
Address Output Enable 3 to 0
These bits select enabling or disabling of address outputs
A8 to A23 in ROMless extended mode and modes with
ROM.
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.
