A versatile five-channel DMA controller is available in the system, accesses memory using the XDATA memory
space, and thus has access to all physical memories. Each channel (trigger, priority, transfer mode, addressing
mode, source and destination pointers, and transfer count) is configured with DMA descriptors that can be
located anywhere in memory. Many of the hardware peripherals (AES core, flash controller, USARTs, timers,
ADC interface, etc.) can be used with the DMA controller for efficient operation by performing data transfers
between a single SFR or XREG address and flash/SRAM.
