3.3.3.2
BVIOL — Boundary Violation
This flag provides information about media activity at slot boundaries (either the end or the beginning of
the current slot). Note that this is not necessarily an error condition, as a semantically valid frame can be
received between the slot boundaries, provided that the idle conditions before and after the frame are
fulfilled.
0 – No media activity detected at slot boundaries.
1 – Media activity detected at slot boundaries.
3.3.3.3
CERR — Content Error
This flag indicates the reception of a semantically incorrect frame.
0 – No content error occurred in current slot.
1 – Content error occurred in current slot.
3.3.3.4
SERR — Syntax Error
This flag indicates the reception of a syntactically incorrect frame.
0 – No syntax error occurred in current slot.
1 – Syntax error occurred in current slot.
3.3.3.5
SUPF — Startup Frame Indication
This flag indicates the reception of a frame header having its startup bit set.
0 – No syntactically correct startup frame received in current slot.
1 – Syntactically correct startup frame received in current slot.
3.3.3.6
NULLF — NULL Frame Indication
This flag indicates the reception of a frame header having its null frame indication bit set.
0 – No syntactically correct null frame received in current slot.
1 – Syntactically correct null frame received in current slot.
3.3.3.7
SYNCF — SYNC Frame Indication
This flag indicates the reception of a frame header having its sync frame indication set.
