19 8-bit basic timer (TIM4, TIM6)
19.1 Introduction
The timer consists of an 8-bit auto-reload up-counter driven by a programmable prescaler. It
can be used for time base generation, with interrupt generation on timer overflow.
TIM6 is implemented with the clock/trigger controller for timer synchronization and chaining.
Refer to Section 17.3 on page 139 for the general description of the timer features.
