WebJul 9, 2024 · The first threshold is the Transmit FIFO Almost Full (set by the TX FIFO Control 1 register). If the number of bytes filled into the FIFO reaches this level, the radio can provide an interrupt for the MCU to start the packet transmission. The second threshold is the Transmit FIFO Almost Empty (set by the TX FIFO Control 2 register). WebOct 6, 2010 · Almost empty: rx_almost_empty: The number of unread entries in the FIFO buffer before the buffer is empty. When the level of the FIFO buffer reaches this threshold, the MAC function asserts the ff_rx_a_empty signal. The MAC function stops reading from the FIFO buffer and subsequently stops transferring data to the user application to avoid ... WebIn addition to the EMPTY, ALMOST_EMPTY, FULL, and ALMOST_FULL flags, a count vector can be enabled to provide a more granular measure of the FIFO state. For the write domain the vector is WR_COUNT[W:0], and for the read domain it is RD_COUNT[R:0]. The width of these vec-tors are user programmable to provide easy generation of additional … maserati mc20 specs 0-60

Looking at the waveform the FIFO has a fall-trough time of ~14 clocks. The behavior of the status flags after a reset seems such that it gives a 'safe' state (See below). For details you have to ask Xilinx about that. I am only worried about the 'X' from the tb_wr_rst_busy.

WebJun 26, 2016 · To detect full and empty is simple: FULL: WP-RP = 4'b1000. EMPTY: WP-RP=4'b0000. We cannot decide full and empty conditions based on MSB.
