Notes: 1. NWR1 enables upper byte writes. NWR0 enables lower byte writes.
2. NWRx enables corresponding byte x writes. (x = 0, 1, 2 or 3)
3. NBS0 and NBS1 enable respectively lower and upper bytes of the lower 16-bit word.
4. NBS2 and NBS3 enable respectively lower and upper bytes of the upper 16-bit word.
