Use of the Konnex standard when using the FEI

0 -> normal mode

1 -> Konnex standard => Br = 32.7 kbps This modifies OSR

Make the sync and acquisition threshold programmable, and allow

the change of the barker code:

0 -> threshold are hard-coded and sync loss counter is 50 bits

1 -> threshold are defined by BParam_Sync_thres and

BParam_Trac_thres

Sync loss counter is variable and defined by

ADParam_Sync_loss

Threshold for sync acquisition in baker mode

Disable data bidir

0 -> Pad Data used in bidirectional mode.

1 ->Pad Data used as output and Pad datain used as input.

Threshold for tracking baker mode

Reserved

ADParam_Sync_loss

6-0 10010 Number of bits before sync loss for barker decoding algorithm.
