channel are connected to ADC input channel.
This is according to the following sections:
• Section 18.2: ADC main features
• Section 18.3.8: Channel selection (CHSEL, SCANDIR, CHSELRMOD)
• Section 18.9: Temperature sensor and internal reference voltage
• Section 18.10: Battery voltage monitoring

12.3.10 From comparators (COMP1/COMP2) to timers
(TIM1/TIM2/TIM16/TIM17)
Purpose
Comparators (COMP1/COMP2) output values can be connected to timers
TIM1/TIM2/TIM16/TIM17 input captures or TIMx_ETR signals.
Comparators (COMP1/COMP2) output values can also generate break input signals for
timer TIM1 on input pins TIMx_BKIN or TIMx_BKIN2 through GPIO alternate function
selection using open drain connection of I/Os.
The possible connections are given in the following sections:
• Section 25.4.23: TIM1 option register 1 (TIM1_OR1)
• Section 25.4.28: TIM1 Alternate function register 2 (TIM1_AF2)
• Section 26.4.22: TIM2 option register 1 (TIM2_OR1)
• Section 26.4.23: TIM2 alternate function option register 1 (TIM2_AF1)
• Section 27.4.21: TIM17 alternate function register 1 (TIM17_AF1)
Active power modes
