On my foray into SAM D land I've come to the to the clock system county..
Am I correct in my assumption/conclusion that the clock system - clock sources, generic clock generators, clock multiplexers - is specific for SAM Ds rather than being something specified and designed by ARM?
The question is asked partly because of pure curiosity, but mainly because of "the duality of the documentation" - i.e. some by/at/from ARM and some by/at/from Atmel/MCPH.
In the SAM D data sheets there are often references to ARM documentation, but I saw none in the chapters and parts dealing with the clock system. And I've looked around for ARM documentation of the M0+ and surrounding ARM design elements but found nothing resembling the clock system on the SAM Ds. Hence my assumption/conclusion. Am I correct?
