TMS570LC4357: How to clear pending interrupt

Ralph Neumann

Part Number: TMS570LC4357

Hello,
how can i clear a pending interrupt flag, before i enable interrupts?
The processor is in Supervisor Mode and a write of 1 to INTREQ[0:3] (as described in SPNU563A) to clear it has no effect.

Regards

Hello,

If the processor is in privileged mode then it should be possible to change INTQREQ[0:3].

You need to clear the interrupt request at its source first and then in the VIM before enabling CPU to respond to interrupt requests.
