Thanks for your code Erich. I was keen to use the watchdog timer because it
works with the lowest power mode (power down) and doesn't need external
components.

It seems to be a fairly common method. The watchdog can either generate a
reset or trigger an interrupt, or both. This interrupt can also be used as
a wake up from power down. (At least on the 324P that I'm using).

The other way I was considering was with timer 2 in synchronous mode (so I
don't need external components) and use power save mode. Did you ever look
at synchronous mode?

Many thanks,

David
