Direct Memory Access (DMA) is a very efficient
mechanism of copying data between peripheral SFRs
(e.g., UART Receive register, Input Capture 1 buffer),
and buffers or variables stored in RAM, with minimal
CPU
automatically copy entire blocks of data without
requiring the user software to read or write the
peripheral Special Function Registers (SFRs) every
time a peripheral interrupt occurs. The DMA controller
uses a dedicated bus for data transfers and, therefore,
does not steal cycles from the code execution flow of
the CPU. To exploit the DMA capability, the
corresponding user buffers or variables must be
located in DMA RAM.
The PIC24HJXXXGPX06A/X08A/X10A peripherals
that can utilize DMA are listed in Table 8-1 along with
their associated Interrupt Request (IRQ) numbers.

Preliminary
TABLE 8-1:
The DMA controller features eight identical data
transfer channels.
Each channel has its own set of control and status
registers. Each DMA channel can be configured to
copy data either from buffers stored in dual port DMA
RAM to peripheral SFRs, or from peripheral SFRs to
buffers in DMA RAM.
The DMA controller supports the following features:
• Word or byte sized data transfers.
• Transfers from peripheral to DMA RAM or DMA
• Indirect Addressing of DMA RAM locations with or
• Peripheral Indirect Addressing – In some
• One-Shot Block Transfers – Terminating DMA
• Continuous Block Transfers – Reloading DMA RAM
• Ping-Pong Mode – Switching between two DMA
• Automatic or manual initiation of block transfers
• Each channel can select from 19 possible sources
For each DMA channel, a DMA interrupt request is
generated when a block transfer is complete. Alterna-
tively, an interrupt can be generated when half of the
block has been filled.
