It is clocked by the 128 kHZ LSI internal RC clock source, and thus stays active even in case
of a CPU clock failure
The IWDG time base spans from 60 µs to 1 s.
Auto wake-up counter

Beeper
The beeper function outputs a signal on the BEEP pin for sound generation. The signal is in
the range of 1, 2 or 4 kHz.
TIM1 - 16-bit advanced control timer
This is a high-end timer designed for a wide range of control applications. With its
complementary outputs, dead-time control and center-aligned PWM capability, the field of
applications is extended to motor control, lighting and half-bridge driver.
