'1': The corresponding bit is ignored for pattern comparison
'0': normal operation (bit comparison enabled)
'1': TS16 CAS Evaluation enabled
'0': TS16 CAS Evaluation disabled
'1': TS16 CAS Evaluation operates on send path input
'0': TS16 CAS Evaluation operates on receive path input
Inversion of selected flag bit, "Active" means an enabled time slot.
A change of this bit means a change of the incoming TS 16 flag bit.
'1': flag bit is active '0'
'0': flag bit is active '1'
Selection of flag bit (MSB of TS 16 is bit 7):
"00": En/Disable via D-Bit (bit 4 and bit 0 of TS 16 are evaluated)
"01": En/Disable via C-Bit (bit 5 and bit 1 of TS 16 are evaluated)
"10": En/Disable via B-Bit (bit 6 and bit 2 of TS 16 are evaluated)
"11": En/Disable via A-Bit (bit 7 and bit 3 of TS 16 are evaluated)
'1': Freeze (no update) of flag bits
'0': normal operation
