RO

pma_tx_pll_is_

locked

Indicates that the TX PLL is locked to the input

reference clock.

1

RW

reset_tx_

digital

Writing a 1 causes the internal TX digital reset signal

to be asserted. You must write a 0 to clear the reset

condition.

2

RW

reset_rx_analog

Writing a 1 causes the internal RX analog reset signal

to be asserted. You must write a 0 to clear the reset

condition.

3

RW

reset_rx_

digital

Writing a 1 causes the internal RX digital reset signal

to be asserted. You must write a 0 to clear the reset

condition.
