Hi 

I want to modify the function that is called when a trap occurs.

The trap I want to modify is to be precise, the ESR1 trap.

I'd like to ask what doc should I read to find out which functions are called when a trap occurs, or information about the trap.

I am using TC387AE.

Thanks in advance.

Hi Kim,

AURIXTC3XX_um_part1_v2.0.pdf,  Section 9.2 Trap Gerneration (TR) describes the TRAPSET TRAPCLR TRAPSTAT TRAPDIS registers which are for ESRx pins' transition to trigger a CPU trap.

Section 9.1.4 Exnternal reset sources and indications, which describes ESR pin functions: reset request trigger / wakeup trigger / reset indication output / trap request trigger
