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

0x0XXX Defines general purpose USB status and control registers

0x1XXX Defines registers that are specific to Endpoint setup and control

0x2XXX Defines the registers used for REGIO accesses to the DSP register space

0x3XXX Defines the MCU program memory write address space
