I'm using ATMEGA406 from ATMEL. This micro controller is one of the battery management family with battery charging and monitoring features. ADC CCADC Battery protection FET control CELL balancing and ... I just to know when measurement of voltage or current,the pwm should be stopped? Thanks

Hi, I want to make a battery charger LiIon with a micro controller. I study about Li-Ion battery, charging methods and ... LiIon should be charge with Constant Current/Constant Voltage method. So we should be able to control current and voltage of charger. So I use PWM for controlling these signals. PWM On/Off Fets for charging with determined current and voltage and with ADC we measured the voltage and current. After reading the current and voltage, the duty cycle must be changed if needed(change with PWM). Now I want know, Should be stop the PWM when I want to measure voltage and current?If yes, why? or if no, why? please help me.
