WebDec 22, 2024 · 6.8.1 OSC clock supply. There are four ways to configure the pins corresponding to the external high-speed clock (HSE): MCO from ST-LINK (Default): MCO output of ST-LINK is used as input clock. This frequency cannot be changed, it is fixed at 8MHz and connected to the PF0/PH0-OSC_IN of STM32 microcontroller. WebElectrical Engineering questions and answers. Suppose the HSE (high-speed external clock) of 16 MHz is selected as the clock of the timer. In order to generate a 1Hz square wave with duty cycle of 50%, how would you set up the timer? Indicate your counting mode and show the value of ARR, CCR, and PSC registers.
