24.2.1. Avalon® -MM Write Agent to Avalon® -MM Read Agent
In this configuration, the input is a zero-address-width Avalon® -MM write agent. An Avalon® -MM write host pushes data into the FIFO core by writing to the input interface, and a read host (possibly the same host) pops data by reading from its output interface. The input and output data must be the same width.
If Allow backpressure is turned on, the waitrequest signal is asserted whenever the data_in host tries to write to a full FIFO buffer. waitrequest is only deasserted when there is enough space in the FIFO buffer for a new transaction to complete. waitrequest is asserted for read operations when there is no data to be read from the FIFO buffer, and is deasserted when the FIFO buffer has data. You must ensure that the FIFO is not empty using the Empty bit field of the status register before performing a read operation on FIFO output interface.
