0x044
[31:0]
RW
reset_fine_control
You can use the
reset_fine_
control
register to create your own
reset sequence. The reset control
module performs a standard reset
sequence at power on and whenever
the
phy_mgmt_clk_reset
is asserted.
Bits [31:4,0] are reserved.
[31:4,0]
RW
Reserved
It is safe to write 0s to reserved bits.
[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.
[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.
[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.
PMA Channel Control and Status
0x061
[31:0]
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.
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 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>.
