TIM6 introduction

The basic timer TIM6 consists of a 16-bit auto-reload counter driven by a programmable
prescaler.
It may be used as a generic timer for time-base generation but it is also specifically used to
drive the digital-to-analog converter (DAC). In fact, TIM6 is internally connected to the DAC
and is able to drive it through its trigger outputs.

TIM6 main features

●
16-bit auto-reload upcounter
● 16-bit programmable prescaler used to divide (also "on the fly") the counter clock
frequency by any factor between 1 and 65535
●
Synchronization circuit to trigger the DAC
●
Interrupt/DMA generation on the update event: counter overflow
