USB Interface

EZ-Host has two built in Host/Peripheral SIEs and four USB transceivers that meet the USB 2.0 specification requirements for full and low speed (high speed is not supported). In Host mode, EZ-Host supports four downstream ports, each support control, interrupt, bulk, and isochronous transfers. In Peripheral mode, EZ-Host supports one peripheral port with eight endpoints for each of the two SIEs. Endpoint 0 is dedicated as the control endpoint and only supports control transfers. Endpoints 1 though 7 support interrupt, bulk (up to 64 bytes/packet), or isochronous transfers (up to 1023 Bytes/packet size). EZ-Host also supports a combination of Host and Peripheral ports simultaneously as shown in Table 3.
