21 / 117 page  DocID025832 Rev 5 21/117 STM32F042x4 STM32F042x6 Functional overview 27 3.12 Timers and watchdogs The STM32F042x4/x6 devices include up to five general-purpose timers and an advanced control timer. Table 7 compares the features of the different timers. 3.12.1 Advanced-control timer (TIM1) The advanced-control timer (TIM1) can be seen as a three-phase PWM multiplexed on six channels. It has complementary PWM outputs with programmable inserted dead times. It Table 6.
