All endpoints (except endpoint 0) can be configured either as Bulk, Interrupt or Isochronous. See
Table 39-1. UDPHS Endpoint
The maximum packet size they can accept corresponds to the maximum endpoint size.
Note: The endpoint size of 1024 is reserved for isochronous endpoints.
The size of the DPRAM is 4 KB. The DPR is shared by all active endpoints. The memory size
required by the active endpoints must not exceed the size of the DPRAM.
SIZE_DPRAM = SIZE _EPT0
If a user tries to configure endpoints with a size the sum of which is greater than the DPRAM,
then the EPT_MAPD is not set.
The application has access to the physical block of DPR reserved for the endpoint through a
KB logical address space.
The physical block of DPR allocated for the endpoint is remapped all along the
address space. The application can write a
