Description

The Interlaken PHY IP requires the use

of the embedded reset controller to

initiate the correct the reset sequence. A

hard reset to

phy_mgmt_clk_reset

and

mgmt_rst_reset

is required for

Interlaken PHY IP.
Altera does not recommend use of a soft

reset or the use of these reset register bits

for Interlaken PHY IP.

[3]

RW

reset_rx_digital

Writing a 1 causes the RX digital reset

signal to be asserted, resetting the RX

digital channels enabled in

reset_ch_

bitmask

. You must write a 0 to clear the

reset condition.

[2]

RW

reset_rx_analog

Writing a 1 causes the internal RX

digital 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.

RW

phy_serial_loopback

Writing a 1 to channel <

n

> puts channel

<

n

> in serial loopback mode. For

information about pre- or post-CDR

serial loopback modes, refer to

Loopback Modes.

RW

pma_rx_set_

locktodata

When set, programs the RX CDR PLL to

lock to the incoming data. 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.
