Data Size.
0: 8-bit memory data path to the PC Card.
1: 16-bit memory data path to the PC Card.
Zero Wait State.
0: System memory access will occur with additional wait states.
1: System memory access will occur with no additional wait states and the NOWS# signal will be
returned to the system bus. The WAIT# signal from PC Card will override this bit.
