(1) The registers in this column are Peripheral Frame 2 Registers.
(2) The ADC result registers are dual mapped in the F28044 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.
