VSUP voltage acquisition of MC9S12ZVC,When the ADC carries out VSUP voltage acquisition,The VSUP voltage is several times the ADC value,I didn't see it in the manual.You can tell me if you know where it is.

Thank you!

Pin Input Divider Ratio2
RatioVSUP = VSUP / VADC
5.5V < VSUP < 29 V

Ratio VSUP = 9
