option bits, the watchdog is automatically enabled at power-on, and generates a reset
unless the key register is written by software before the counter reaches the end of count.
Auto-wakeup counter
This counter is used to cyclically wakeup the device in Active-halt mode. It can be clocked by
the internal 128 kHz internal low-frequency RC oscillator or external clock.
LSI clock can be internally connected to TIM3 input capture channel 1 for calibration.
Beeper
This function generates a rectangular signal in the range of 1, 2 or 4 kHz which can be
output on a pin. This is useful when audible sounds without interference need to be
generated for use in the application.
Advanced control and general purpose timers
STM8A devices described in this datasheet, contain up to three 16-bit advanced control and
general purpose timers providing nine CAPCOM channels in total. A CAPCOM channel can
be used either as input compare, output compare or PWM channel. These timers are
named TIM1, TIM2 and TIM3.
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.

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
Up/down 1 to 65536
