RW

pma_rx_set_locktoref

When set, programs the RX CDR PLL to

lock to the reference clock. Bit <

n

>

corresponds to channel <

n

>. By default,

the Interlaken PHY IP configures the

CDR PLL in Auto lock Mode. This bit is

part of the CDR PLL Manual Lock Mode

which is not the recommended usage.

RO

pma_rx_is_

lockedtodata

When asserted, 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

>.

00x067

[31:0]

RO

pma_rx_is_

lockedtoref

When asserted, indicates that the RX
