The PIC32 Direct Memory Access (DMA) controller is a
bus master module useful for data transfers between
different devices without CPU intervention. The source
and destination of a DMA transfer can be any of the
memory mapped modules existent in the PIC32 (such
as Peripheral Bus (PBUS) devices: SPI, UART, PMP,
etc.) or memory itself.
Following are some of the key features of the DMA
controller module:
• Four identical channels, each featuring:
