WAIT
Wait State Insertion
When WAIT is set, the W89C840AF, as a bus master, executes
memory read/write with one wait state every data phase. When
WAIT is reset, the W89C840AF, 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

CA
Cache Alignment
CA defines the address boundary for the burst access to the
transmission or receive data.
When the starting address of the data burst access is not aligned,
more specifically, the starting address should be a multiple of
some number such as 4, 8 etc., the W89C840AF will have the
first burst transfer that causes that the next burst access will has
the start address aligned.
After the first burst occurred, all other burst operation are
aligned with the configuration of CA accordingly.
The CA must be initialized with a non zero value after reset.
The alignment configuration is as following:
[15:14] Address Alignment
-----------------------------------------------------
[00] reserved
[01] 8 long-word alignment
[10] 16 long-word alignment
[11] 32 long-word alignment
