Snooze not working

[kladogen]

I'm using snooze on PIC16LF1705 in a low power project.
I call
Snooze 6 to place the PIC in low power for ~2 secs but the program just freezes and never reaches the next instruction. Eventually the program restarts after about 8-10 secs.
The sleep command, when I set the watchdog to 8 secs and call sleep it works correctly.

Is there something special that I need to do to use snooze.

Hi,
It would probably help if you posted your code.

Thanks for your replies.

In the end I used WDTE_SWDTEN in config and Sleep after setting the watchdog to 1 sec.

If WDTE_SWDTEN config is not set you cant modify the watchdog timings.
