FBD to LAI Signal Mapping

The following example show how an FBD Southbound Command Frame is transferred

from FBD frame format to LA Interface early/late data.

The LAI interface delays the SB “A slot” by one clock to capture the FBD frame in the

same “ABC” slot format that is sent from the host - rather than the “BCA” (B and C slots

from host frame N-1 plus A slot from host frame N) used by the normal mode AMBs to

minimize latency on the decode of slot A commands.
