The following is a DMA initialization example:
EXAMPLE 7-1:
© 2007 Microchip Technology Inc.
// Clear all DMA controller status bits to a known state
// Set up DMA Channel 0: Word mode, Read from Peripheral & Write to DMA; Interrupt when all the
data has been moved; Indirect with post-increment; Continuous mode with Ping-Pong Disabled
// Set up offset into DMA RAM so that the buffer that collects ADC result data starts at the base
of DMA RAM
// DMA0PAD should be loaded with the address of the ADC conversion result register
// DMA transfer of 256 words of data
//Clear the DMA0 Interrupt Flag
//Enable DMA0 Interrupts
//Enable the DMA0 Channel
//Automatic DMA transfer initiation by DMA request; DMA Peripheral IRQ Number set up for ADC1
