Description
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
