6.4. Transceiver Reconfiguration Signals
The Avalon® memory-mapped interface implements a standard memory-mapped protocol. You can connect an Avalon® master to this bus to access the registers of the embedded Transceiver PHY IP core.
|reconfig_clk||Input||Avalon® clock. The clock frequency is 100- 161 MHz. All signals transceiver reconfiguration interface signals are synchronous to reconfig_clk .|
|reconfig_reset||Input||Resets the Avalon® memory-mapped interface and all of the registers to which it provides access.|
|reconfig_write||Input||Write enable signal. Signal is active high.|
|reconfig_read||Input||Read enable signal. Signal is active high.|
PMA reconfiguration interface address bus. For more information, refer to the E-Tile Transceiver PHY User Guide.
|reconfig_writedata[31:0]||Input||A 32-bit data write bus. reconfig_address specifies the address.|
|reconfig_readdata[31:0]||Output||A 32-bit data read bus. Drives read data from the specified address. Signal is valid after reconfig_waitrequest is deasserted.|
|reconfig_waitrequest||Output||Indicates the Avalon® memory-mapped interface is busy. Keep the reconfig_write or reconfig_read asserted until reconfig_waitrequest is deasserted.|
