WebDriver for a peripheral clocked from APB can request the APB frequency to be set to 80 MHz while the peripheral is used. RTOS can request the CPU to run at the highest configured frequency while there are tasks ready to run. A peripheral driver may need interrupts to be enabled, which means it will have to request disabling light sleep. WebLicences.
