68300

Just going through some old notes, and I noticed that at one time I
calculated 22.118400 MHz as a nice number: it allows you to run the UARTs
(SCI and TPU) at all the standard baud rates with no error.  Using the PLL,
it can be generated 38.400 kHz rock.  38.4 kHz also gives you a even 100 Hz
PIT rate, something 32.768 kHz can't.

So why does everyone seem to use 32.768 kHz?  Availability?

(For that matter, my next '332 design will probably use a 4.9152 MHz and a
'4060, instead of a low frequency tuning fork rock.)
