Register 0x60 sets the high byte of the base I/O address for
chip select 0.
Bits [7:0] =Address[15:8]
Note: Bits[15:12] must be ‘0’ since the chip performs 16-bit
address qualification on the base I/O addresses.
Register 0x61 sets the low byte of the base I/O address for chip
select 0.
Bits[7:0] = Address[7:0]
Register 0x62 sets the high byte of the base I/O address for
chip select 1.
Bits [7:0] =address[15:8]
Note: Bits[15:12] must be ‘0’ since the chip performs 16-bit
address qualification on the base I/O addresses.
