When asserted, all digital and analog circuitry in the PCS,
HSSI, CDR, and PCIe modules are powered down.
Asserting the gxb_powerdown signal does not power down
the refclk buffers.
When asserted, the transmitter PCS blocks are reset.
When asserted, analog circuitry in the receiver PMA block is
reset.
When asserted, the receiver PCS blocks are reset.
Also used for offset cancellation except in PIPE mode.
For the supported frequency range for this clock, refer to
Cyclone IV Device Data Sheet
A high level during BIST test mode indicates the verifier either
receives complete pattern cycle or detects an error and stays
asserted until being reset using the rx_digitalreset
port.
A high level during PRBS test mode indicates the verifier
receives complete pattern cycle and stays asserted until being
reset using the rx_digitalreset port.
In BIST test mode, the signal stays asserted upon detecting an
error until being reset using the rx_digitalreset port.
In PRBS test mode, the signal asserts for a minimum of 3
rx_clkout clock cycles upon detecting an error and
deasserts if the following PRBS sequence contains no error.
