Hi,
a friend of mine has taken a look to the data sheet and reference manual of the MK66FX1M0D18
and the schematics of the board and asked me two question which I cannot find a valid answer.
1) Schematics of the Teensy 3.6: "Why is VREG_OUT _and_ the LP38691 both connected to VDD -
didn't that imply, that two regulators (the LP... and the regulator VREG_OUT) would push/pull both
on VDD? Where can I find informations on using VREG_OUT in the documentation of the processor?
2) General: "How can it be, that the clock frequency can be choosen via the IDE? Normally the IDE
is used to select, what one _have_ and there is no selector of that kind?"
*) "IDE" => Arduino IDE
I myself has tried to answer the questions via the datasheet and the reference manual -- but I didn't find sufficient ones...
How can I answer the questions ?
Thanks a lot for any help in advance!
Cheers!
