Hello Expert,

This question is related to the following e2e.

CC2340R5: The initialization sequence code with TCXO.

I received the following initial setting information .

in CKM, set HFXTCTL.TCXOMODE = 1
set HFXTCTL.TCXOTYPE to the correct type (clipped sine / cmos)
enable HFXT by setting HFXTCTL.EN = 1

Is this same for XO (non Temperature compensated XO)?

Hi Fujinaka-san,

No there is no setting change required if you're just using a standard crystal oscillator.

Hello Jake,

Sorry, my question was wrong.

I mean, normal XO (no temperature compensated type) , not crystal oscillator.

In that case if the output from your oscillator is the same as from a TCXO but without temperature compensation then the configuration would remain the same. The system can't tell from the clock source whether or not it's temperature compensated.
