Field
Description
Tn_IE
Trigger n Interrupt Enable
SAF_CNT_B_EN If this bit is set the counter used to check the conversion time is enabled
SAF_CNT_A_EN If this bit is set the counter used to check the conversion time is enabled
DMA_DE
If this bit is set, a dma done is like a write in the gre bit. If it is at 0 you have to write the gre
bit (if something is changed in the double buffered register) otherwise you will have an error
on the next master reload.
MRS_DMAE DMA transfer Enable on MRS occurrence if GRE bit is set
MRS_IE
MRS Interrupt Enable
IEE
Interrupt Error Enable
