AT91SAM9R64/RL64 Preliminary
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
