Timers

The medium-density STM8AL313x/4x/6x and STM8AL3L4x/6x devices contain one

advanced control timer (TIM1), two 16-bit general purpose timers (TIM2 and TIM3) and one

8-bit basic timer (TIM4).

All the timers can be served by DMA1.

Table 3 compares the features of the advanced control, general-purpose and basic timers.

3.13.1

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.

•

16-bit up, down and up/down auto reload counter with 16-bit prescaler

•

Three independent capture/compare channels (CAPCOM) configurable as input

capture, output compare, PWM generation (edge and center aligned mode) and single

pulse mode output.

•

One additional capture/compare channel which is not connected to an external I/O

•

Synchronization module to control the timer with external signals

•

Break input to force timer outputs into a defined state

•

Three complementary outputs with adjustable dead time

•

Encoder mode

•

Interrupt capability on various events (capture, compare, overflow, break, trigger)

3.13.2

16-bit general purpose timers

•

16-bit auto reload (AR) up/down-counter

•

7-bit prescaler adjustable to fixed power of 2 ratios (1…128)

•

Two individually configurable capture/compare channels

•

PWM mode

•

Interrupt capability on various events (capture, compare, overflow, break, trigger)

•

Synchronization with other timers or external signals (external clock, reset, trigger and

enable)
