Hello,The chip I use is mpc5777C, the IDE is S32DS2.1, and the program is added in the attachment. When I debug the Decrementer interrupt (interrupt number 10), the program will run away.
Proceed as follows:
First initialize the HID0 register, TSR, TCR register;
Then initialize IVPR and IVOR10;
Finally, the program will jump to IVOR10_Handler;
Please help me solve how the program jumps to interrupt No. 10 and executes related functions.
