ENBYSYNC_xC= 1 Enables Receiver Byte Synchronization for Channel
xC. ENBYSYNC_xC = 0 on device reset.
ENBYSYNC_xD = 1 Enables Receiver Byte Synchronization for Channel
xA. ENBYSYNC_xD = 0 on device reset.
LCKREFN_xC = 0 Locks the receiver PLL to reference clock for Channel
xC.
LCKREFN_xC =1 = Locks the receiver to data for Channel xx.
NOTE: When LCKREFN_xx = 0, the corresponding LKI_xx bit is also 0.
LCKREFN_xC = 0 on device reset.
LCKREFN_xD = 0 Locks the receiver PLL to reference clock for Channel
xD.
LCKREFN_xD =1 = Locks the receiver to data for Channel xA.
NOTE: When LCKREFN_xx = 0, the corresponding LKI_xx bit is also 0.
LCKREFN_xD = 0 on device reset.
Enable Loopback Mode for Channel xC. When LOOPEN_xC=1, the
transmitter high-speed output is looped back to the receiver high-speed
input. This mode is similar to high-speed loopback mode enabled by
TESTMODE_xx except that LOOPEN_xx disables the high-speed serial
output. LOOPEN_xC=0 on device reset.
Enable Loopback Mode for Channel xD. When LOOPEN_xD=1, the
transmitter high-speed output is looped back to the receiver high-speed
input. This mode is similar to high-speed loopback mode enabled by
TESTMODE_xx except that LOOPEN_xx disables the high-speed serial
output. LOOPEN_xD=0 on device reset.
Word Align Disable Bit. When NOWDALIGN_xC=1, receiver word align-
ment is disabled for Channel xC. NOWDALIGN_xC=0 on device reset.
Word Align Disable Bit. When NOWDALIGN_xD=1, receiver word align-
ment is disabled for Channel xD. NOWDALIGN_xD=0 on device reset.
