Advanced control and general purpose timers
TIM1: 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 bridge driver.

Basic timer
The typical usage of this timer (TIM4) is the generation of a clock tick.

8-bit
16-bit up, down and up/down AR (auto-reload) counter with 16-bit fractional prescaler.
Four independent CAPCOM channels configurable as input capture, output compare,
PWM generation (edge and center aligned mode) and single pulse mode output
Trigger module which allows the interaction of TIM1 with other on-chip peripherals. In
the present implementation it is possible to trigger the ADC upon a timer event.
External trigger to change the timer behavior depending on external signals
Break input to force the timer outputs into a defined state
Three complementary outputs with adjustable dead time
Interrupt sources: 4 x input capture/output compare, 1 x overflow/update, 1 x break
16-bit auto-reload up-counter
15-bit prescaler adjustable to fixed power of two ratios 1…32768
Timers with three or two individually configurable CAPCOM channels
Interrupt sources: 2 or 3 x input capture/output compare, 1 x overflow/update
8-bit auto-reload, adjustable prescaler ratio to any power of two from 1 to 128
Clock source: master clock
Interrupt source: 1 x overflow/update
Up/down 1 to 65536
