When enabled and triggered, receive flow control is initiated to limit the CPGMAC_SL from further frame reception. Half-duplex mode receive flow control is collision based while full duplex mode issues 802.3X pause frames. In either case, receive flow control prevents frame reception by issuing the flow control appropriate for the current mode of operation. Receive flow control is enabled by the RX_FLOW_EN bit in the SL_MACCONTROL register. Receive flow control is triggered (when enabled) when the RX_FLOW_TRIGGER input is asserted. The CPGMAC_SL is configured for collision or IEEE 802.3X flow control via the FULLDUPLEX bit in the SL_MACCONTROL register.
