Set the lock bit by programming bit 16 in the DMACCxConfiguration Register.
When a burst occurs, the AHB arbiter must not de-grant the master during the burst until
the lock is deasserted. The GPDMA can be locked for a a single burst such as a long
source fetch burst or a long destination drain burst. The GPDMA does not usually assert
the lock continuously for a source fetch burst followed by a destination drain burst.

These values are reserved and should not be used.
Reserved, do not modify, masked on read.
Destination peripheral. This value selects the DMA destination request peripheral.
This field is ignored if the destination of the transfer is to memory. See the
SrcPeripheral symbol description for values.
Reserved, do not modify, masked on read.
Flow control and transfer type. This value indicates the flow controller and transfer
type. The flow controller can be the GPDMA, the source peripheral, or the
destination peripheral.The transfer type can be memory-to-memory,
memory-to-peripheral, peripheral-to-memory, or peripheral-to-peripheral.

Terminal count interrupt mask. When cleared this bit masks out the terminal count
interrupt of the relevant channel.
Lock. When set, this bit enables locked transfers.
Active. This value can be used with the Halt and Channel Enable bits to cleanly
disable a DMA channel. Writing to this bit has no effect.
There is no data in the FIFO of the channel.
The channel FIFO has data.
Halt. The contents of the channel FIFO are drained. This value can be used with the
Active and Channel Enable bits to cleanly disable a DMA channel.
Enable DMA requests.
Ignore further source DMA requests.
Reserved, do not modify, masked on read.
Source peripheral. This value selects the DMA source request peripheral.This field
