The Rx clock stop interface allows the Rx portion of the UDMA to be gracefully commanded to shut down its operations and enter into an IDLE state so that the main clock (FICLK) can be stopped. When the rcs_clkstop_req input is asserted, the Rx portion of the UDMA will stop processing receive packets for each channel at the next packet boundary. Once all of the Rx channels have gracefully stopped reception, the UDMA will assert the rcs_clkstop_ack output. Once the UDMA Rx engine has entered the IDLE state, it will remain there until the rx_clockstop_req is de-asserted.
