P.E. K70 Clock setup. MCG External Osc selection

crezyoz — Sat, 21 Jul 2012 08:33:05 GMT

Why is system osc 0 the only external clock available in the MCG clk source settings? From the diagram in figure 5.1 it appears I should be able to select osc 1 as well.

Thanks. It seems I should be able to use OSC1 as well but from what I understand it requires multiple clock modes to be switched through in order to get it to work. ? I am uneasy about that so I have temporarily hacked an external OSC on my board to use OSC0. I look forward to your help with this.

Hi,

Does Freescale have FORMAL release sample code for this issue? I have the same problem ?

I use CW 10.5 and K70 & KINETIS_120MHZ_SC!

Thanks!!

Regards,

Mark
