VREF_OUT usage on KL03?

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
