NOTES:
1) Register addresses 16h to 1Fh do not exist.
2) In the Serial Port Mode, the LSB is on the right hand side.
3) In the Serial Port Mode, data is read and written LSB first.
4) In the Serial Port Mode, the A bit (the LSB) determines whether the access is a read (A = 1) or a write
(A = 0).
5) In the Serial Port Mode, the B bit (the MSB) determines whether the access is a burst access (B = 1)
or a single register access (B = 0).
