STM8S Reload Watchdog Timer During Halt Mode

Hey guys,

I am using an STM8S003F3 and am trying to implement a watchdog timer. I have been using the IWDG functions from the standard peripheral library and it seems to work, but once I enter HALT mode I can't reset the watchdog timer. I want to be able to have the watchdog timer running during HALT mode, but according to the datasheet I cannot wake up from HALT mode using the watchdog timer or a timer interrupt. Does anyone have any insight into how to incorporate a watchdog timer when HALT mode is being used?

Thank you!
