Well, my *previous* clock was on the Mega 2560 (an AVR chip, although
admittedly one with more code space and IO than usual). I made some
mention of it back in 2012. It had 500ns timer granularity and no Rb
(just DPLL of a timer running off of the onboard crystal) but it still
managed well enough :)
