4.1 Memory regions accessible by the GPDMA
4.2 GPDMA functional description
This chapter describes the major functional blocks of the GPDMA. It contains the following
sections:
Table 649. GPDMA accessible memory
[1]
The GPDMA enables peripheral-to-memory, memory-to-peripheral,
peripheral-to-peripheral, and memory-to-memory transactions. Each DMA stream
provides unidirectional serial DMA transfers for a single source and destination. For

Supports 8, 16, and 32 bit wide transactions.
Big-endian and little-endian support. The GPDMA defaults to little-endian mode on
reset.
An interrupt to the processor can be generated on a DMA completion or when a DMA
error has occurred.
Interrupt masking. The DMA error and DMA terminal count interrupt requests can be
masked.
Raw interrupt status. The DMA error and DMA count raw interrupt status can be read
prior to masking.
Test registers for use in block and integration system level testing.
Identification registers that uniquely identify the GPDMA. These can be used by an
operating system to automatically configure itself.
