MCU registers are defined in four memory spaces grouped by the following address ranges:

0x0XXX This address range defines general-purpose USB status and control registers

0x1XXX This address range defines registers that are specific to Endpoint setup and control

0x2XXX This address range defines the registers used for REGIO accesses to the DSP register space

0x3XXX This address range defines the MCU program memory write address space
