FEAC[5:0]
FEAC[5:0] contain the six bit code that is transmitted on the FEAC channel (FEAC). The
transmitted code consists of a sixteen bit sequence that is repeated continuously. The
sequence consists of eight ones followed by a zero, followed by the six bit code sequence
transmitted in order FEAC0, FEAC1, .., FEAC5, followed by a zero. The all-ones sequence is
inserted in the FEAC channel when FEAC[5:0] is written with all ones.
Note: If configured for J2 transmission format (TFRM[1:0] is 10 binary) and any of LCDEN,
AISEN, OOFEN, LOSEN are set to logic one in the S/UNI-JET Data Link and FERF/RAI
Control, FEAC[5:0] in this register must all be set to logic one for proper RAI transmission
upon detection of LCD, PHYAIS, LOF, or LOS by the J2 FRMR. Otherwise, the BOC code
configured by the FEAC[5:0] bits of this register will be transmitted instead of the RAI.
