The SSIEx registers stilldefine which channels are to have B7 stuffing preformed1 = source signaling data as enabled by the SSIEx registersBit 5/Transmit CRC Pass Through (TCPT).0 = source CRC6 bits internally1 = CRC6 bits sampled at TSER during F-bit timeBit 6/Transmit F-Bit Pass Through (TFPT).0 = F bits sourced internally1 = F bits sampled at TSERBit 7/Transmit Japanese CRC6 Enable (TJC).0 = use ANSI/AT&T/ITU CRC6 calculation (normal operation)1 = use Japanese standard JT–G704 CRC6 calculation43 of 242
