There are two solutions that can be used to force the transmit interface into alignment.
Set the TX_DELAY_VALUE to 1 or higher while keeping TX_DELAY_TYPE = TIME.
When any delay value is given, BISC will force the transmitter into alignment. By giving a non-zero value, BISC forces the alignment for the TX_BITSLICEs.
Use the RXTX_BITSLICE where the RX_DELAY_TYPE and TX_DELAY_TYPE are both accessible.
Ensure that the RX_DELAY_FORMAT & TX_DELAY_FORMAT are both set to TIME.
