DMA configuration

[Omkar9903]

Hi,

I am using s32k96 UC & configured of dmaLogicChannel_Type_0 with CH16 using DMA_IP_HW_INST_1 interrupt.

I have attached the one image I want to change the ISR time but not getting which parameter is configure for ISR time.

BR Omkar.

Hi @Omkar9903 

It is not possible to control the timing of the DMA ISR by simply setting a parameter. However, you can generate a periodic DMA trigger event using the PIT or when a transmit buffer becomes empty or a receive buffer becomes full, periodically. Refer to section 13.4.2.1 (Enable a source with periodic triggering) of the S32K39 and S32K37 Reference Manual, Rev. 3.

Could you provide more details on the implementation you are looking for?
