first off
can_disable was designed to work with at90can seriers so might not work
with your uC
Other than the timer, I'm not sure what canfestival can do to wake the
controller up, but i have zero experience with sleep, so keep that in mind.
Before sleep I think it is best to set the node in stop mode. It just
disable processing and making of almost every type of canopen message, and
it will also tell the network that is has stopped.
On start, what you have done looks good to me.
best regards
Lars
