PFCR is an 8-bit read/write register that controls the CS selection of pins PG4 and PG1, controls
LCAS selection of pins PF2 and PF6, and controls the address output in expanded mode with
ROM.
PFCR is initialized to H'0D/H'00 by a power-on reset and in hardware standby mode. It retains its
previous state by a manual reset or in software standby mode.
Bit 7—CS0/CS7 Select (CSS07): This bit selects the contents of CS output via the PG4 pin. In
modes 4, 5, and 6, setting the corresponding DDR to 1 outputs the selected CS.
Bit 7
CSS07 Description
0 Selects CS0 (Initial value)
