Well, yes I would tend to agree.
But on the other hand, an open question means you can answer pretty much what you want.
For instance when PORT was mentioned, I biased my answer to suggest the TIMER.
Give it a go Peg, it's my training for politics
I would push even further. On devices with ECLK available, it is possible to output exactly the bus speed.
Oh, and if you use the SCI, the maximum is Bus Speed/16. This is because the bits are sampled 16 times to make up the fact that no clock signal is available on SCI lines.
My answers are now: Bus; Bus/2; Bus/4 and Bus/16.
The COP would be nasty in my previous C code suggested at it would also make the RESET pin toggle.
