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
Macrotick Counter — protocol related variable:
This field provides the macrotick count of the current communication cycle.
Cycle Counter — protocol related variable:
This field provides the number of the current communication cycle. If the counter reaches the maximum value
of 63, the counter wraps and starts from zero again.
