ACEB Aggregated Content Error on Channel B — This flag is set when a content error has been detected on
channel B. Content errors are detected in the communication slots, the symbol window, and the NIT.
0 No content error detected.
1 Content error detected.
ASEB Aggregated Syntax Error on Channel B — This flag is set when a syntax error has been detected on
channel B. Syntax errors are detected in the communication slots, the symbol window and the NIT.
0 No syntax error detected.
1 Syntax errors detected.
AVFB Aggregated Valid Frame on Channel B — This flag is set when a syntactically correct valid frame has been
received in any static or dynamic slot through channel B.
1 At least one syntactically valid frame received.
0 No syntactically valid frames received.
WUA Wakeup Symbol Received on Channel A — This flag is set when a wakeup symbol was received on
channel A.
0 No wakeup symbol received.
1 Wakeup symbol received.
ABVA Aggregated Boundary Violation on Channel A — This flag is set when a boundary violation has been
detected on channel A. Boundary violations are detected in the communication slots, the symbol window, and
the NIT.
0 No boundary violation detected.
1 Boundary violation detected.
AACA Aggregated Additional Communication on Channel A — This flag is set when a valid frame was received in
a slot on channel A that also contained an additional communication with either syntax error, content error, or
boundary violations.
0 No additional communication detected.
1 Additional communication detected.
ACEA Aggregated Content Error on Channel A — This flag is set when a content error has been detected on
channel A. Content errors are detected in the communication slots, the symbol window, and the NIT.
0 No content error detected.
1 Content error detected.
ASEA Aggregated Syntax Error on Channel A — This flag is set when a syntax error has been detected on channel
A. Syntax errors are detected in the communication slots, the symbol window, and the NIT.
0 No syntax error detected.
1 Syntax errors detected.
AVFA Aggregated Valid Frame on Channel A — This flag is set when a syntactically correct valid frame has been
received in any static or dynamic slot through channel A.
0 No syntactically valid frames received.
1 At least one syntactically valid frame received.
