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
TIM2 - 16-bit general purpose timer
TIM4 - 8-bit basic timer
16-bit up, down and up/down autoreload counter with 16-bit prescaler
Four independent capture/compare channels (CAPCOM) configurable as input capture,
output compare, PWM generation (edge and center aligned mode) and single pulse mode
output
Synchronization module to control the timer with external signals
Break input to force the timer outputs into a defined state
Three complementary outputs with adjustable dead time
Encoder mode
Interrupt sources: 3 x input capture/output compare, 1 x overflow/update, 1 x break
16-bit autoreload (AR) up-counter
15-bit prescaler adjustable to fixed power of 2 ratios 1…32768
3 individually configurable capture/compare channels
PWM mode
Interrupt sources: 3 x input capture/output compare, 1 x overflow/update
8-bit autoreload, adjustable prescaler ratio to any power of 2 from 1 to 128
Clock source: CPU clock
