Terminal Count interrupt usage.

Hi,

I am using LPC4330 based board. I am trying to do DMA to transfer data from I2S to Memory.

While trying to understand the working of the DMA, I came across Terminal Count Interrupt.

My question stems from a lack of understanding of when this terminal count interrupt is generated.

Is this interrupt generated whenever the DMA controller transfers data after a BREQ signal is raised from the peripheral? OR
Is this interrupt generated after all required size of data is transferred from the peripheral to the memory?

Thanks,
Milind
