Connector/Jack location bits
This field describes the location of the jack in the system.
0h - Rear I/O Panel
1h - Front Panel
2h - Motherboard
3h - Dock/External
4h:6h - Reserved
7h - No Connection/unused I/O
These bits are Read/Write.
Sensed bits meaning relates to the I/O being sense as output or inputs.
Sensed bits (outputs): See Table 25: page75.
This field allows for the reporting of the type of output peripheral/device plugged in
the jack. Values specified below should be interrogated in conjunction with the
SR[5:0] and OR[1:0] bits for accurate reporting.
Sensed bits (inputs): See Table 26: page75.
This field allows for the reporting of the type of input peripheral/device plugged in
the jack. Values specified below should be interrogated in conjunction with the
SR[5:0] and OR[1:0] bits for accurate reporting.
This field is Read Only.

Over-ride Register 2Ah, D12 write-lock when SPDIF_EN = 1.
All bits except SPDIF sample-rate are affected (D13-D12). Allows for sub-code
changing on-the-fly.
SPDIF Digital Output Source Selection:
DO1 = 0; PCM data from the AC-Link to SPDIF
DO1 = 1; ADC record data to SPDIF
