I am using 'MC912ZVL32' series. Need to monitor the voltage range from 9 to 16V. For that configured 10 bit ADC with ref voltage as 5V but unable to find out the internal resistive divider of VSUP to ADC.
Below are my observed values at different voltages
VBATT Voltage VSUP voltage ADC value
9V 7.82 V 201
12V 11.2 V 271
16V 15.6V 367.
Based on the above values the relation differs for the voltage and unable to find out the relation in the Reference manual.
It just mentioned as
Kindly let me know if any one knows the Internal resistive divider value.
