5. Programming the GPDMA

User manual
5.1 Enabling the GPDMA
5.2 Disabling the GPDMA
Table 651. DMA Connections
The GPDMA enables peripheral-to-memory, memory-to-peripheral,
peripheral-to-peripheral, and memory-to-memory transactions. Each DMA stream is
configured to provide unidirectional DMA transfers for a single source and destination.
The source and destination areas can each be either a memory region or a peripheral
which supports the GPDMA, and must be accessible through AHB1.
The following applies to the registers used in the GPDMA:
To enable the GPDMA set the DMA Enable bit in the DMACConfiguration Register
(Section 32–6.1.13 “Configuration Register (DMACConfiguration - 0xFFE0
To disable the GPDMA:

Reserved or unused address locations must not be accessed because this can result
in unpredictable behavior of the device.
Reserved or unused bits of registers must be written as zero, and ignored on read
unless otherwise stated in the relevant text.
All register bits are reset to a logic 0 by a system or power-on reset unless otherwise
stated in the relevant text.
Unless otherwise stated in the relevant text, all registers support read and write
accesses. A write updates the contents of a register and a read returns the contents
of the register.
All registers defined in this document can only be accessed using word reads and
word writes (i.e. 32 bit accesses), unless otherwise stated in the relevant text.
