(1) The registers in this column are Peripheral Frame 2 Registers.
(2) The ADC result registers are dual mapped in the 280x DSP. Locations in Peripheral Frame 2 (0x7108-0x7117) are 2 wait-states and left
justified. Locations in Peripheral frame 0 space (0x0B00-0x0B0F) are 0 wait sates and right justified. During high-speed/continuous
conversion use of the ADC, use the 0 wait-state locations for fast transfer of ADC results to user memory.
