Function Description
Parameters
void DMA_ITConfig (
DMAy_Channelx, uint32_t DMA_IT,
NewState)
Enables or disables the specified DMAy Channelx interrupts.

DMAy_Channelx : where y can be 1 or 2 to select the DMA
and x can be 1 to 7 for DMA1 and 1 to 5 for DMA2 to select
the DMA Channel.

DMA_IT : specifies the DMA interrupts sources to be
enabled or disabled. This parameter can be any combination
of the following values:

DMA_IT_TC :

DMA_IT_HT :

DMA_IT_TE :

NewState : new state of the specified DMA interrupts. This
parameter can be: ENABLE or DISABLE.

None.

None.
FlagStatus DMA_GetFlagStatus ( uint32_t DMAy_FLAG)
Checks whether the specified DMAy Channelx flag is set or not.

DMAy_FLAG : specifies the flag to check. This parameter
can be one of the following values:

DMA1_FLAG_GL1 :

DMA1_FLAG_TC1 :
flag.

DMA1_FLAG_HT1 :

DMA1_FLAG_TE1 :

DMA1_FLAG_GL2 :

DMA1_FLAG_TC2 :
flag.

DMA1_FLAG_HT2 :

DMA1_FLAG_TE2 :

DMA1_FLAG_GL3 :

DMA1_FLAG_TC3 :
flag.
