Notes:
1. Byte access - Even. In this x8 mode, D0-D7 contain the
"even" byte (low byte) of the x16 word. D8-D15 are inactive.
2. Byte access - Odd. In this x8 mode, D0-D7 contain the "odd"
byte (high byte) of the x16 word. This is accomplished inter-
nal to the card by transposing D8-D15 to D0-D7. D8-D15
are inactive.

3. Odd byte only access. In this x8 mode, D8-D15 contain the
"odd" byte (high byte) of the x16 word. D0-D7 are inactive.
A0 = X.
4. Word access. In this mode D0-D7 contain the "even" byte
while D8-D15 contain the "odd" byte. A0 = X
