The following table shows the miscellaneous status and control signals.

Table 1. Miscellaneous Status/Control Signals
Name Direction Clock Domain Description
ctl_tx_test_pattern_enable Input tx_clk_out

Test pattern generation enable for the TX core. A value of 1 enables test mode.

Corresponds to MDIO register bit 3.42.3 as defined in clause 45. Takes second precedence.

ctl_tx_test_pattern_select Input tx_clk_out Corresponds to MDIO register bit 3.42.1 as defined in Clause 45
ctl_tx_data_pattern_select Input tx_clk_out Corresponds to MDIO register bit 3.42.0 as defined in Clause 45
ctl_tx_test_pattern_seed_a[57:0] Input tx_clk_out Corresponds to MDIO registers 3.34 through to 3.37 as defined in Clause 45
ctl_tx_test_pattern_seed_b[57:0] Input tx_clk_out Corresponds to MDIO registers 3.38 through to 3.41 as defined in Clause 45
ctl_rx_test_pattern_enable Input rx_clk_out

Test pattern enable for the RX core. A value of 1 enables test mode.

Corresponds to MDIO register bit 3.42.2 as defined in Clause 45. Takes second precedence.

ctl_rx_data_pattern_select Input rx_clk_out Corresponds to MDIO register bit 3.42.0 as defined in Clause 45.
stat_rx_test_pattern_mismatch Output rx_clk_out Test pattern mismatch increment. A non-zero value in any cycle indicates how many mismatches occurred for the test pattern in the RX core. This output is only active when ctl_rx_test_pattern is set to a 1. This output can be used to generate MDIO register as defined in Clause 45. This output is pulsed for one clock cycle.
ctl_local_loopback Input Async Sets GT in near-end PMA loopback
ctl_rx_process_lfi Input rx_clk_out

When this input is set to 1, the RX core expects and processes LF control codes coming in from the transceiver.

When set to 0, the RX core ignores LF control codes coming in from the transceiver.

stat_rx_valid_ctrl_code Output rx_clk_out Indicates that a PCS block with a valid control code was received.
