Precision Internal Reference of ADC and On-chip Clock Generator problems in XMC1300

[#1]

Dear Sir,
How can I set the Precision Internal Reference of ADC, just as 4.096V or 2.048V and On-chip Clock Generator problems, just as 32MHz or 48MHz, in XMC1300 series CPU.

See Chapter 16 of the Reference manual:

According to the Fig. 16-8, The internal reference is a range, not a precision voltage, isn't it ? or, may I have a example about this ?
By the way, On-chip Clock Generator problems, just as 32MHz or 48MHz, in XMC1300 series CPU, has any response ?
Thank you very much.

The nominal internal reference is 5V. You should adjust the AREF setting bit according to your supply voltage.

For XMC1300, the maximum frequency of the core is 32MHz.
