Direct Memory Access (DMA) is a very efficient mech-
anism 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
intervention. The DMA controller can automatically
copy entire blocks of data without requiring the user
software to read or write the peripheral Special Func-
tion 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 dsPIC33FJ32MC302/304, dsPIC33FJ64MCX02/
X04 and dsPIC33FJ128MCX02/X04 peripherals that
can utilize DMA are listed in Table 8-1.
