Hi,
I was wondering if it was possible to configure a peripheral to be in non-secure mode and have the interrupt handler associated with the peripheral run in secure mode?
Basically by not setting the appropriate bit in NVIC_ITNSn.
Best,
Rajiv
There is no need to change the CONTROL and EXC_RETURN if the mode and state before and after the ISR are the same. The EXC_RETURN has been extended to support additional information about security states, so all the Secure ISR can be implemented as normal C function.
