What is the default value of interrupt priority of ADC, I2C, PINT, CAN, etc.. if not set to any value?

Hello Hemanth,

The default value of interrupt priority of ADC, I2C, PINT, CAN is 0, where 0 is the highest priority.

Hello Alice,

Among the default value of interrupt priority for the peripherals, which peripheral would have higher priority?

i.e. Non of the peripheral are configured for Interrupt priority, then in that case all are of high priority "0" then how is the priority among peripherals?

Hello Hemanth,

"which peripheral would have higher priority?", same priority, system will priority run the interrupt

that first Interrupted.

About the detail interrupt, recommend you have a look at <ARM Cortex-M4 Processor Technical Reference Manual>at ARM website:
