PRODUCTION DATA
The HB-8 FIFO Mode uses 8 bits of data, removes ALE and address pins, and optionally adds external FIFO Full/Empty flag inputs. This scheme is used by many devices, such as radios, communication devices (including USB2 devices), and some FPGA configuration (FIFO through block RAM). This FIFO Mode presents the data side of the normal Host-Bus interface, but is paced by FIFO control signals. It is important to consider that the FIFO Full/Empty control inputs may stall the EPI interface and can potentially block other CPU or DMA accesses. For more detailed maps of the HB-8 FIFO Mode, see Table 7-7.
