    I there was a problem in the application MC9S12XET256 chip:When the CPU has frequently CAN interrupt and a serial port interrupt occurs, the program will occasionally in crash situation.When back to normal after close the COP, is there a better handle this suggestion?

    And why the program crashes, does not automatically produce watchdog reset? whether you need to do in watchdog interrupt processing can trigger watchdog reset
