Shall be cleared to zero.
Shall be set to one.
= device detected CBLID- above ViH ? 80 wired cable
= device detected CBLID- below ViL
Device 1 hardware reset result. Device 0 shall clear these bits to zero.
Device 1 shall set these bits as follows:
Reserved.
= Device 1 did not assert PDIAG-
= Device 1 asserted PDIAG-.
Bit 10-9 These bits indicate how Device 1 determined the device number:

= Reserved.
= a jumper was used.
= the CSEL signal was used.
= some other method was used or the method is unknown.
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:
Reserved.
= Device 0 does not respond when Device 1 is selected.
= Device 0 responds when Device 1 is selected.
= Device 0 did not detect the assertion of DASP-.
= Device 0 detected the assertion of DASP-.
= Device 0 did not detect the assertion of PDIAG-.
= Device 0 detected the assertion of PDIAG-.
= Device 0 failed diagnostics.
= Device 0 passed diagnostics.
These bits indicate how Device 0 determined the device number:
= Reserved.
= a jumper was used.
= the CSEL signal was used.
= some other method was used or the method is unknown.
Shall be set to one.
8.6.27 Word 128: Security status
