Clock control
The STM8TL53C4/G4 embed a robust clock controller. It is used to distribute the system
clock to the core and the peripherals and to manage clock gating for low power modes. This
system clock is a 16-MHz High Speed Internal RC oscillator (HSI RC), followed by a
programmable prescaler.
In addition, a 38 kHz low speed internal RC oscillator is used by the Independent watchdog
(IWDG) and Auto-wakeup unit (AWU).
Independent watchdog
The independent watchdog (IWDG) peripheral can be used to resolve processor
malfunctions due to hardware or software failures.
It is clocked by the 38 kHz LSI internal RC clock source, and thus stays active even in case
of a CPU clock failure.
Window watchdog
The window watchdog (WWDG) is based on a 7-bit downcounter that can be set as free-
running. It can be used as a watchdog to reset the device when a problem occurs. It is
clocked from the main clock. It has an early warning interrupt capability and the counter can
be frozen in debug mode.
Auto-wakeup counter
The auto-wakeup (AWU) counter is used to wakeup the device from Active-halt mode.
General purpose and basic timers
STM8TL53C4/G4 devices contain two 16-bit general purpose timers (TIM2 and TIM3) and
one 8-bit basic timer (TIM4).
16-bit general purpose timers
The 16-bit timers consist of 16-bit up/down auto-reload counters driven by a programmable
prescaler. They perform a wide range of functions, including:
●
●
●
●
●
8-bit basic timer
The 8-bit timer consists of an 8-bit up auto-reload counter driven by a programmable
prescaler. It can be used for timebase generation with interrupt generation on timer overflow.
Timebase generation
Measuring the pulse lengths of input signals (input capture)
Generating output waveforms (output compare, PWM and One pulse mode)
Interrupt capability on various events (capture, compare, overflow, break, trigger)
Synchronization with other timers or external signals (external clock, reset, trigger and
enable)
