I want to use the WDT interrupt in wdt counter 0 and WDT reset in wdt counter 1 but after initialize, it will go to infinite loop can't reset.

   

If I just enable EDT interrupt in wdt counter 0, it will no problem.  Below is my config code of the watchdog timer

   

    CySysWdtDisable(CY_SYS_WDT_COUNTER0_MASK);
    while (CySysWdtReadEnabledStatus(0));

   

    CySysWdtWriteMode(CY_SYS_WDT_COUNTER0,CY_SYS_WDT_MODE_INT);
    CySysWdtWriteMatch(CY_SYS_WDT_COUNTER0,WDT_INTERVAL_1MS); // WDT interval  Timer = 1msec in counter 0
    CySysWdtWriteClearOnMatch(CY_SYS_WDT_COUNTER0, 1u);
    CySysWdtWriteCascade(CY_SYS_WDT_CASCADE_NONE);
    
    //Enable WDT counter 0 
    CySysWdtEnable(CY_SYS_WDT_COUNTER0_MASK);

   

    CySysWdtWriteMode(CY_SYS_WDT_COUNTER1,CY_SYS_WDT_MODE_INT);
    CySysWdtWriteMatch(CY_SYS_WDT_COUNTER1,WDT_1S); // WDT Timer = 1sec in counter 1
    CySysWdtWriteClearOnMatch(CY_SYS_WDT_COUNTER1, 1u);
    CySysWdtWriteCascade(CY_SYS_WDT_CASCADE_NONE);

   

    //Enable WDT counter 1 
    CySysWdtEnable(CY_SYS_WDT_COUNTER1_MASK);

   

    // Lock WDT registers
    CySysWdtLock();

Hi Bob,

   

Because the code have a confidential of our company's patented technology, I can't released the complete project to you.

   

Can you provide a sample code using the wdt counter0 for the 1ms interval interrupt timer and wdt counter1 for 1sec reset counter.

   

Thanks.

Hi Bob,

   

I think I can enable the WDT reset timer.  When the WDT Reset occured, the PC will go to 0x10000046.

   

Please advise.  Thanks.
