You can use the reset_fine_control register to create
your own reset sequence. The reset control module,
illustrated in
reset sequence at power on and whenever the
phy_mgmt_clk_reset is asserted. Bits [31:4, 0] are
reserved.
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.
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.
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.
Writing a 1 to channel <n> puts channel <n> in serial
loopback mode.
When channel <n> =1, indicates that receive circuit for
channel <n> senses the specified voltage exists at the RX
input buffer. This option is only operational for the PCI
Express PHY IP core.
When set, programs the RX CDR PLL to lock to the
incoming data. Bit <n> corresponds to channel <n>.
When set, programs the RX CDR PLL to lock to the
reference clock. Bit <n> corresponds to channel <n>.
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>.
When asserted, indicates that the RX CDR PLL is locked to
the reference clock. Bit <n> corresponds to channel <n>.
Specifies lane or group number for indirect addressing
which is used for all PCS control and status registers. For
variants that stripe data across multiple lanes, this is the
logical group number. For non-bonded applications, this is
the logical lane number.
