Direct Memory Access (DMA) is a very efficient
mechanism of copying data between peripheral SFRs
(e.g., the UART Receive register and 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 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 peripherals that can utilize DMA are listed in
Table 8-1 along with their associated Interrupt Request
(IRQ) numbers.
