Port Function Control Register 2 (PFCR2)
PFCR2 is an 8-bit readable/writable register that performs I/O port control. PFCR2 is initialized to
H'30 by a reset, and in hardware standby mode.
Bits 7 and 6—Reserved: Only 0 should be written to these bits.
Bit 5—CS167 Enable (CS167E): Enables or disables CS1, CS6, and CS7 output. For details, see
section 8.12, Port G.
Bit 4—CS25 Enable (CS25E): Enables or disables CS2, CS3, CS4, and CS5 output. Change the
CS25E setting only when the DDR bits are cleared to 0. This bit is valid in modes 4 to 6.
