Word Content Description

93Hardware reset result. The contents of bits (12:0) of this word shall change only during the execution of a hardware reset

15:Shall be cleared to zero.

14:Shall be set to one.

13:1 = device detected CBLID- above ViH. 0 = device detected CBLID- below ViL

12-8: Device 1 hardware reset result. Device 0 shall clear these bits to zero. Device shall set these bits as follows:

12: Reserved.

11:0 = Device 1 did not assert PDIAG-. 1 = Device 1 asserted PDIAG-.

10-9: These bits indicate how Device 1 determined the device number:

00 = Reserved.

01 = a jumper was used.

10 = the CSEL signal was used.

11 = some other method was used or the method is unknown.

8: Shall be set to one.

7-0: Device 0 hardware reset result. Device 1 shall clear these bits to zero. Device shall set these bits as follows:

7: Reserved.

6:0 = Device 0 does not respond when Device 1 is selected.

1 = Device 0 responds when Device 1 is selected.

5:0 = Device 0 did not detect the assertion of DASP-.

1 = Device 0 detected the assertion of DASP-

4:0 = Device 0 did not detect the assertion of PDIAG-.

1 = Device 0 detected the assertion of PDIAG-.

3:0 = Device 0 failed diagnostics. 1 = Device 0 passed diagnostics.

2-1: These bits indicate how Device 0 determined the device number:

		00	= Reserved.
		01	= a jumper was used.
		10	= the CSEL signal was used.
		11	= some other method was used or the method is unknown.
		0: Shall be set to one.
94	15-8:	Vendor’s recommended acoustic management value.
	7-0:	Current automatic acoustic management value
95	Stream Minimum Request Size
96	Stream Transfer Time - DMA
