Figure 37. Avalon® Memory-Mapped Interface Tab in Parameter Editor
Parameter | Values | Description |
---|---|---|
Enable Avalon® Memory Mapped Interface | On/Off | Enables or disables the Avalon® memory mapped interface. Default value is Off. You must enable this setting for Transceiver Toolkit support. |
Enable Direct PHY soft CSR | On/Off | Enables or disables the soft CSR feature. Default value is Off. You must enable this setting for Transceiver Toolkit support. |
Enable readdatavalid port on Avalon® interface | On | Indicates data valid. This port is always enabled when Avalon® memory-mapped interface is used.. |
Enable separate Avalon® interface per PMA | On/Off | Off specifies shared Avalon® interface. On specifies split interface, if multiple interfaces available with selected targets. Default value is Off. |
Enable Debug Endpoint on Avalon® interface | On/Off | When On, the GTS PMA/FEC Direct PHY IP includes an embedded Debug Endpoint that internally connects Avalon® memory-mapped agent interface. The Debug Endpoint can access the reconfiguration space of the FEC and the PMA interface block. The IP can perform certain tests and debug functions through JTAG using the System Console. This option may require that you include a jtag_debug link in the system. Default value is Off. You must enable this setting for Transceiver Toolkit support. |
