Programming Information
Bit Name
Default
Bit No.
Type
= 0: The F-bit is compared with the target activate/deactivate inband loopback code, but the result of the F-bit comparison is discarded.
= 1: The F-bit is skipped in the comparison process.
These two bits define the length of the target deactivate inband loopback code, meanwhile, they define the valid code in the DACT[7:0] bits
