Timing, They need to know the speed of the clock so they can determine the 
timing for programming the flash.  IE 6 counts at 20Mhz and 12 counts at 
10MHz in some internal timing loop.

The information has to come from somewhere.  The Analog Devices chips don't 
need it (in a similar case) since they only allow a single Xtal frequency.
