Automatic CRC4 Bit Inversion
If set, all CRC bits of one outgoing submultiframe are inverted in case
a CRC error is flagged for the previous received submultiframe. This
function is logically ored with RC0.XCRCI.
Transmit CRC4 Bit Inversion
If set, the CRC bits in the outgoing data stream are inverted before
transmission. This function is logically ored with RC0.CRCI.

Standard operation. Three or four consecutive incorrect service
words (depending on bit RC0.ASY4) causes loss of
synchronization.
Errors in service words have no influence when in synchronous
state. However, they are used for the resynchronization
procedure.
Standard operation. Three consecutive incorrect FAS words or
three consecutive incorrect service words causes loss of
synchronization.
Four consecutive incorrect FAS words or four consecutive
incorrect service words causes loss of synchronization. The
service word condition is disabled by bit RC0.SWD.
