25 / 117 page  DS12992 Rev 2 25/117 STM32G031x4/x6/x8 Functional overview 31 3.15 Voltage reference buffer (VREFBUF) 3.16 Timers and watchdogs The device includes an advanced-control timer, five general-purpose timers, two low-power timers, two watchdog timers and a SysTick timer. Table 7 compares features of the advanced-control, general-purpose and basic timers. 3.16.1 Advanced-control timer (TIM1) The advanced-control timer can be seen as a three-phase PWM unit multiplexed on 6 channels. It has complementary PWM outputs with programmable inserted dead-times. It When enabled, an embedded buffer provides the internal reference voltage to analog blocks (for example ADC) and to VREF+ pin for external components. The internal voltage reference buffer supports two voltages: • 2.048 V • 2.5 V An external voltage reference can be provided through the VREF+ pin when the internal voltage reference buffer is disabled. On some packages, the VREF+ pad of the silicon die is double-bonded with supply pad to common VDD/VDDA pin and so the internal voltage reference buffer cannot be used. Table 7.
