Check whether the specified DMA Stream interrupt is enabled or not.

Parameters
__HANDLE__DMA handle
__INTERRUPT__specifies the DMA interrupt source to check. This parameter can be one of the following values:
  • DMA_IT_TC: Transfer complete interrupt mask.
  • DMA_IT_HT: Half transfer complete interrupt mask.
  • DMA_IT_TE: Transfer error interrupt mask.
  • DMA_IT_FE: FIFO error interrupt mask.
  • DMA_IT_DME: Direct mode error interrupt.
Return values
Thestate of DMA_IT.

Writes the number of data units to be transferred on the DMA Stream.

Parameters
__HANDLE__DMA handle
__COUNTER__Number of data units to be transferred (from 0 to 65535) Number of data items depends only on the Peripheral data format.
Note
If Peripheral data format is Bytes: number of data units is equal to total number of bytes to be transferred.
If Peripheral data format is Half-Word: number of data units is equal to total number of bytes to be transferred / 2.
If Peripheral data format is Word: number of data units is equal to total number of bytes to be transferred / 4.
Return values
Thenumber of remaining data units in the current DMAy Streamx transfer.
