In FIFO less mode of Triple-Speed Ethernet (IP), does the TSE IP discard erroneous frames when the RX_ERR_DISC bit in the command_config register is set to 1?


No. Triple-Speed Ethernet (TSE)  IP does not discard any erroneous frames even when both RX_ERR_DISC is set to 1 and rx_section_full is set to 0 for store and forward mode.

To discard erroneous frames, Internal FIFO is necessary and the TSE IP must behave as store&forward mode with setting the rx_section_full to zero.
