USB DSP Register Definitions
For each endpoint, four registers are defined to provide a memory
buffer in the DSP. These registers are defined for each endpoint
shared by all defined interfaces, for a total of 4 ؋ 8 = 32 registers.
These registers are read/write by the DSP only. They are
described in Table 11.
