VREF_OUT usage on KL03?

[chucksmith]

Hello,  I'm a bit confused about the VREF_OUT usage on the KL03. The reference guide says we can write a 1 to REF_SEL to choose VALTHI/VALTLO as the alternate reference pair. On the KL03 does this select VREF_OUT as the (internally generated) ADC voltage reference? And if so, if we are only using VREF_OUT as the internal ADC reference, do we still need the 100nf Cap?

Thanks,

Chuck

Hi Chuck,

On the KL03 does this select VREF_OUT as the (internally generated) ADC voltage reference?
Yes. You can find below information from it's Reference Manual KL03P24M48SF0RM.

And if so, if we are only using VREF_OUT as the internal ADC reference, do we still need the 100nf Cap?
Yes.

Best Regards,

Robin
