The PIC24HJ32GP302/304 devices contain 1 Kbytes
of dual ported DMA RAM located at the end of X data
space.
PIC24HJ128GPX02/X04 devices contain 2 Kbytes of
dual ported DMA RAM located at the end of X data
space, and is a part of X 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.
