Hi Ti support

     If I let the watchdog  do not has reset action but let it produce an interrupt, what is the entrance address of this interrupt.

#define  MSS_RTIA_REGISTER_BASE   0x02F7A000

#define MSS_RTIWWDRXNCTRL_OFFSET 0xA4 /*bit0-3：WWDRXN 0x5-> reset; 0xA -> generate a non-maskable interrupt */

    Hi Wang,

    You can check the VIM interrupt vector table to get the address of the ISR's registered for a specific interrupt.

    For each VIM interrupt core, there is an associated interrupt vector table (VIM RAM) that is used to store the address of ISRs. During register vectored interrupt and hardware vectored interrupt, VIM accesses the interrupt vector table using the vector value to fetch the address of the corresponding ISR.

    You can refer to chapter 14 in TRM to get more information on this.

    Regards,
