Figure B-10. USB Endpoint 2 Code Download Base Address Register

Contains an 18 bit address which corresponds to the starting location for

DSP code download on Endpoint 2. This register is read/write by the MCU only. The most significant bit (DS bit) selects either DSP1 PM address space (DS=0) or DSP2 PM address space (DS=1).
