I am trying to disable all interrupts except one like this:

CyGlobalIntDisable; // disable all interrutpts

CySysWdtEnable(CY_SYS_WDT_COUNTER2_MASK); // enable just this one.

is there a better way?

Try using a Global Signal Reference component. This should fire by WDC and leave deep sleep

I am afraid that this will not work.

CyGlobalIntDisable will seta bit in the processor status register to prevent any interrupt from firing (except NMI)

Is there another disable all interrupts function i can use?

Afaik there isn't. EnterCriticalSection() and ExitCriticalSection do the same.

Would be better when you tell a bit more what your problem is.

I want to disable all interrupts before sleep, and wake up from only the WDT2 interrupt and nothing else.
