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 in accordance with the ATA8,
ACS2 specification. See specification for details.
12 – 0b Reserved
11 – 0b 0 = Device 1 did not assert PDIAG-
1 = Device 1 asserted PDIAG-
10–9 – 00b 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 in accordance with the ATA8,
ACS2 specification. See specification for details.
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
