Bits R/W Register Name Description
[2] RW reset_rx_analog Writing a 1 causes the internal RX analog
reset signal to be asserted, resetting the
RX analog logic of all channels enabled in
reset_ch_bitmask. You must write a 0 to
clear the reset condition.
[1] RW reset_tx_digital Writing a 1 causes the internal TX digital
reset signal to be asserted, resetting all
channels enabled in reset_ch_bitmask.
You must write a 0 to clear the reset
condition.

Bits R/W Register Name Description
0x061 [31:0] RW phy _ serial _ loopback Writing a 1 to channel <n> puts channel
<n> in serial loopback mode.
0x063 [31:0] R pma_rx_signaldetect When channel <n> =1, indicates that
receive circuit for channel <n> senses the
specified voltage exists at the RX input
buffer.
0x064 [31:0] RW pma_rx_set_locktodata When set, programs the RX CDR PLL to
lock to the incoming data. Bit <n>
corresponds to channel <n>.
0x065 [31:0] RW pma_rx_set_locktoref When set, programs the RX CDR PLL to
lock to the reference clock. Bit <n>
corresponds to channel <n>.
0x066 [31:0] RO pma_rx_is_lockedtodata When 1, indicates that the RX CDR PLL is
locked to the RX data, and that the RX
CDR has changed from LTR to LTD
mode. Bit <n> corresponds to channel <n>
.
0x067 [31:0] RO pma_rx_is_lockedtoref When 1, indicates that the RX CDR PLL is
locked to the reference clock. Bit <n>
corresponds to channel <n>.
