bit7 : I/O Window 1 Waite State. If this bit is set to “1” or this wait state is set by the wait# signal which is common

bit6 : I/O Window 1 Zero Waite State. If this bit is set to “1”, 8bit system I/O accesses occur with zero additional

bit5 : I/O Window 1 IOCS16# Source. If this bit is set to “0”, IOCS16# signal will be generated based on the value

bit4 : I/O Window 1 data size. “0” indicates 8bit mode, and “1” indicates 16bit mode.

bit3 : I/O Window 0 Wait State. If this bit is set to “1” or this wait state is set by the wait # signal which is common

bit2 : I/O Window 0 Zero Waite State. If this bit is set to “1”, 8bit system I/O accesses occur with zero additional

bit1 : I/O Window 0 IOCS16# Source. If this bit is set to “0”, IOCS16# signal will be generated based on the value

bit0 : I/O Window 0 data size. “0” indicates 8bit mode, and “1” indicates 16bit mode.
