Description (3/3)
[data10]
The source address extended repeat value. The value can be any power of 2, from 2
1
to 2
27
.
Specify PDL_NO_DATA if the extended repeat function is not required for the source address.
[data11]
The destination address extended repeat value. The value can be any power of 2, from 2
1
to 2
27
.
Specify PDL_NO_DATA if the extended repeat function is not required for the destination
address.
[func]
The function to be called when a DMA transfer completes.
Specify PDL_NO_FUNC if not required.
[data12]
The interrupt priority level. Select between 1 (lowest priority) and 15 (highest priority).
This parameter will be ignored if PDL_NO_FUNC is specified for parameter func.
Return value
True if all parameters are valid and exclusive; otherwise false.
Category
EXDMA controller
Reference
None.
Remarks
•
If another peripheral will be used to trigger an EXDMAC transfer, call this function before
calling the Create function for the peripheral.
•
A callback function is executed by the interrupt processing function. This means that no other
interrupt can be processed until the callback function has completed.
•
The EXDMA controller is not available on the 100-pin and 85-pin packages.
