Bit 5: Transmitter Driver Monitor (TDM). This read-only status bit indicates the current state of the transmit driver
monitor. See Section
Bit 4: PRBS Detector Output (PRBS). This read-only status bit indicates the current state of the receiver’s PRBS
detector. See
Bit 1: Receiver Loss of Lock (RLOL). This read-only status bit indicates the current state of the receiver clock
recovery PLL.
Bit 0: Receiver Loss of Signal (RLOS). This read-only status bit indicates the current state of the receiver loss-of-
signal detector.
0 = the transmitter is operating normally
1 = the transmitter amplitude is out of range
0 = in sync with expected pattern
1 = out of sync, expected pattern not detected
0 = the receiver PLL is locked onto the incoming signal
1 = the receiver PLL is not locked onto the incoming signal
0 = signal present
1 = loss of signal
