(1) The registers in this column are Peripheral Frame 2 Registers.
(2) The ADC result registers are dual mapped. Locations in Peripheral Frame 2 (0x7108–0x7117) are 2 wait-states and left justified.
Locations in Peripheral frame 0 space (0x0B00–0x0B0F) are 1 wait-state for CPU accesses and 0 wait state for DMA accesses 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.
