Description
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
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
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
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
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
