Word Bit(s) Setting Default Value Description
93 Shall be 0000h for SATA devices
15 0b Shall be cleared to zero
14 0b Shall be set to one
13 0b 1 = Device detected CBLID-above V
IH
0 = device detected CBLID-below V
IL
Device 1 hardware reset result
Device 0 shall clear these bits to zero
Device 1 shall set these bits as follows:
12 0b Reserved
11 0b 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 un-
known
8 0b Shall be set to one
Device 0 hardware reset result. Device 1 shall clear these
bits to zero.
Device 0 shall set these bits as follows:
7 0b Reserved
6 0b 0 = Device 0 does not respond when Device 1 is selected.
1 = Device 0 responds when Device 1 is selected.
5 0b 0 = Device 0 did not detect the assertion of DASP-
1 = Device 0 detected the assertion of DASP-
4 0b 0 = Device 0 did not detect the assertion of PDIAG-
1 = Device 0 detected the assertion of PDIAG-
3 0b 0 = Device 0 failed diagnostics.
1 = Device 0 passed diagnostics.
2–1 00b 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 un-
known
0 0b Shall be set to one
94 15–8 F 00h Vendor's recommended acoustic management value
7–0 V 00h Current automatic acoustic management value
95 (O)V 0000h Stream Minimum Request Size
