Thank you very much for your help.
I'm using MKM34Z256VLL7 and I'm having trouble with the SAR-ADC initialization.
The source is shown below.
On line 21, set clockSource to kADC16_ClockSourceAlt2, BUSCLOCK/2 =20.97152MHz/2 =10.48576MHz.
(clockDivider = kADC16_ClockDivider8)
Then, in ADC16_DoAutoCalibration(), kADC16_ChannelConversionDoneFlag does not stand, so it becomes an infinite loop.
Please let me know why clockSource = kADC16_ClockSourceAlt2 is not good.
I read in the datasheet that the ADC CONVERSION CLOCK should be less than 18MHz.

The following is omitted.
thank you.
