The PIC32MX 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
PIC32MX (such as Peripheral Bus (PBUS) devices:
SPI, UART, I
Following are some of the key features of the DMA
controller module:
• Four Identical Channels, each featuring:
• Automatic Word-Size Detection:
