00: SM field is generated on-chip.
01: SM field, except BIP-8, is sourced from external FPGA.
BIP-8 is inserted on-chip.
10: SM field is sourced from incoming data.
11: SM field is generated on-chip, except for BEI/BDI,
which are sourced from external FPGA.

00: PSI field is generated on-chip.
01: PSI field is sourced from external FPGA.
10: PSI field is sourced from incoming data.
11: Reserved.
1. When no FPGA is used, FAS is inserted from the default values stored in the on-chip FPGA buffer and zeros are inserted into the
remaining bytes (excluding MFAS and TCMn).
