Thanks Joe.

.zip the .pdf and upload the zip file is the general solution I've heard for the forum being picky.

@kenmac: do you always run at Xtal-5MHz or do you activate the main PLL too when the prop 'wakes up'?

Lawson.
For this particular project speed is not a concern, so I used 5mHz to minimise the current drain.
The Prop's load is dependant on the clock frequency and number of Cog's operating, plus any active I/O load.
In this case the "1 Cog" current is <1mA - there are no I/O controlled by Cog0.
