Hello Shudhamatinarha,

As far as I know, the MCAL package doesn't have API to install the interrupt handler. Use need to do it manually. Normally, the OS will install the interrupt handler.

In the sample app, MCAL team has provided the demo which show how to install the interrupt handler. Please find the sample app in the MCAL package S32K14X_MCAL4_3_RTM_1_0_1.

sys_enableIsrSource(id, priority);
sys_registerIsrHandler(id, (uint32) interrupt_handler);

Best regards,

Hung.
