BIT
FUNCTION
DESCRIPTION
15
BIST Valid
Reflects the validity of the Built In Self Test (BIST) signature. The bit is cleared upon assertion or de-
assertion of the test mode bit in 0x78, bit 14, and set to one upon completion of the BIST. BIST signature
is valid when the bit is one.
14:3
BIST Signature
Built in self test resultant signature.
2:0
Revision Status
Revision status currently 001.
NOTE: Bits listed as reserved should be set to 0 for backwards compatibility.

NOTES:
17. Channel summary fault is the logical or’ing of channel status <10:7,3>.
18. Clear fault by writing “1” to each summary fault bit (15:11).
19. Channel summary status is cleared as well as the Channel status word.
20. Output summary fault clears top status bits <9:0>.
