WAIT
Wait State Insertion
When WAIT is set, W89C841F as a bus master executes
memory read/write with one wait state every data phase.
When WAIT is reset, W89C841F as a bus master executes
memory read/write with zero wait state every data phase.

Descriptor Big Endian Mode
When set, the descriptors will be handled in big endian
mode.
When reset, the descriptors will be treated in little endian
mode
