Notes:
1.Generic register block.
2.Device register block-Rx.
3.Device register block-Tx.
4.Top-level interrupts.
5.Rx control.
6.Tx control signals.
7.Per STS#1 cos flag.
* ADDR values delimited by a comma indicate the address for each of four channels, from channel A to D. For example, the register to Tx con-
trol signals has addresses of 20, 38, 50, and 68. This indicates that channel A Tx control signals are at address 20, control B Tx control sig-
nals are at address
