Measure RMS and frequency with stm32f405

I have to measure current and voltage rms as well as frequency for three phase sinusoidal. 
Is there an application note about measuring rms and/or frequency with the stm32f4 series? I 'm checking the specification and for example for PB0 is written alternate function TIM3_CH3 and additional function ADC12_IN8. Is it possible to use the ADC12_IN18 with combination with the TIM3_CH3 to measure the frequency with the timer and at the same time the rms with the ADC?
