Bit 2: Transmit Driver Monitor Status (TDM) This bits indicates the status of the transmit monitor circuit in the
transmit LIU.
Bit 1: Receive Loss Of Lock Status (RLOL) This bits indicates the status of the receive LIU clock recovery PLL
circuit.
Bit 0: Performance Monitoring Update Status (PMS) This bits indicates the status of all active performance
monitoring register and counter update signals in this port. It is an “AND” of all update status bits and is not set until
all performance registers are updated and the counters reset. In software update modes, the update request bit
PORT.CR1.PMU should be held high until this status bit goes high.
0 = Transmit output not over loaded
1 = Transmit signal is overloaded
1 = Not locked to the incoming signal
0 = The associated update request signal is low
1 = The requested performance register updates are all completed
0 = Locked to the incoming signal
