ETPU - Data Service Request

[mertk]

Hi everyone, 

I wonder does the interrupt for data service request interrupt the CPU, when it interrupts the DMA? I read RM and I think it is not interrupting the CPU while it interrupts the DMA. However, I wanted to ask about it to be sure.

Best regards, 

Mert.

Hi, these are two different things (masked individually), but both events van be issues by eTPU microcode, it depends how it is implemented in the eTPU function.
