Every PIC24HJXXXGPX06/X08/X10 device contains 2
Kbytes of dual ported DMA RAM located at the end of
data space. Memory locations in the DMA RAM space
are accessible simultaneously by the CPU and the DMA
controller module. DMA RAM is utilized by the DMA
controller to store data to be transferred to various
peripherals using DMA, as well as data transferred from

various peripherals using DMA. The DMA RAM can be
accessed by the DMA controller without having to steal
cycles from the CPU.
When the CPU and the DMA controller attempt to
concurrently write to the same DMA RAM location, the
hardware ensures that the CPU is given precedence in
accessing the DMA RAM location. Therefore, the DMA
RAM provides a reliable means of transferring DMA
data without ever having to stall the CPU.
Note:

DMA RAM can be used for general
purpose data storage if the DMA function
is not required in an application.
