DIRECT MEMORY ACCESS
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
intervention.
The
DMA
Controller
can
automatically copy entire blocks of data, without the
user software having to read or write peripheral Special
Function Registers (SFRs) every time a peripheral
interrupt occurs. To exploit the DMA capability, the
corresponding user buffers or variables must be
located in DMA RAM space.
The DMA Controller features eight identical data
transfer channels, each with its own set of control and
status registers. The UART, SPI, DCI, Input Capture,
Output Compare, ECAN and A/D modules can utilize
DMA. Each DMA channel can be configured to copy
data either from buffers stored in DMA RAM to
peripheral SFRs or from peripheral SFRs to buffers in
DMA RAM.
Each channel supports the following features:
Word or byte-sized data transfers
Transfers from peripheral to DMA RAM or DMA
RAM to peripheral
Indirect addressing of DMA RAM locations with or
without automatic post-increment
Peripheral Indirect Addressing – In some
peripherals, the DMA RAM read/write addresses
may be partially derived from the peripheral
One-Shot Block Transfers – Terminating DMA
transfer after one block transfer
Continuous Block Transfers – Reloading DMA
RAM buffer start address after every block
transfer is complete
Ping-Pong Mode – Switching between two DMA
RAM start addresses between successive block
transfers, thereby filling two buffers alternately
Automatic or manual initiation of block transfers
Each channel can select from 32 possible
sources of data sources or destinations
For each DMA channel, a DMA interrupt request is
generated
when
a
block
transfer
is
complete.
Alternatively, an interrupt can be generated when half of
the block has been filled. Additionally, a DMA error trap
is generated in either of the following Fault conditions:
DMA RAM data write collision between the CPU
and a peripheral
Peripheral SFR data write collision between the
CPU and the DMA Controller
