#define __HAL_DMA_RESET_HANDLE_STATE ( __HANDLE__ ) ((__HANDLE__)->State = HAL_DMA_STATE_RESET)

Reset DMA handle state.

Parameters:

__HANDLE__,: specifies the DMA handle.

Return values:

None

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:

The	number of remaining data units in the current DMAy Streamx transfer.
