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
