Special Function Registers with DMA Access only

The DMA can transfer data to any GPR or SFR location. For better user accessibility, some of the more commonly used SFR spaces have their mirror registers placed in a separate data memory location. These mirror registers can be only accessed by the DMA module through the DMA Source and Destination Address registers. The figure below shows the register map for these registers.

These registers are useful to multiple peripherals together like the Timers, PWMs and also other DMA modules using one of the DMA modules.
