Hi Team,
We are using the S32K388 eval board. We want to trigger the non-maskable interrupt when the pin PTD3 value changes.
We have configured PTD3 pin mode as SYSTEM_NMI_B. The pin PTD24 is configured as the GPIO output mode. We have connected the PTD3 & PTD24 via a wire on the IO matrix of the Eval board.
The code is written to toggle the PTD24 pin. Since this pin is connected to PTD3 which is configured as SYSTEM_NMI_B, we were expecting the breakpoint kept inside the NMI_Handler function to hit. But the breakpoint is never hit.
We also have enabled this interrupt using the API NVIC_EnableIRQ(NonMaskableInt_IRQn).
We are using the example code of Icu driver and did the changes as per our requirement.
Is there any other configuration parameter/ any code changes we need to do in order to enable this NMI interrupt?
S32K3 #NMI #Interrupt #ICU
