without having any impact on the timing of “injected” conversions
– “injected” conversions for precise timing and with high conversion priority
3.23 Random number generator (RNG)
All devices embed an RNG that delivers 32-bit random numbers generated by an integrated
analog circuit.
3.24 Timers and watchdogs
The STM32L476xx includes two advanced control timers, up to nine general-purpose
timers, two basic timers, two low-power timers, two watchdog timers and a SysTick timer.
