Normal operation
Power down mode. No RTS values and no transmit clock are
generated.
Normal operation
The clock generated by the PLL is looped into the RTS generator.
Normal operation
The receive clock is looped to the transmit output of the ICRC.
Normal operation
Generated RTS values are looped into the SRTS Receive FIFO.
Normal operation
The clock recovery interface is bypassed. RTS values from the
frame receiver are looped into the SRTS Transmit FIFO.
The PLL is put in power down mode, and a free running clock is
generated. In case pwd is set, all circuits of the port, including the
RTS generator are disabled, no output clock is generated and all
error counters are reset.
