System configuration controller and routing interface
The system configuration controller provides the capability to remap some alternate
functions on different I/O ports. TIM4 and ADC1 DMA channels can also be remapped.
The highly flexible routing interface allows application software to control the routing of
different I/Os to the TIM1 timer input captures. It also controls the routing of internal analog
signals to ADC1, COMP1, COMP2, DAC1 and the internal reference voltage V
provides a set of registers for efficiently managing the charge transfer acquisition sequence

Touch sensing
The high density and medium+ density STM8L15xx devices provide a simple solution for
adding capacitive sensing functionality to any application. Capacitive sensing technology is
able to detect finger presence near an electrode which is protected from direct touch by a
dielectric (glass, plastic, ...). The capacitive variation introduced by the finger (or any
conductive object) is measured using a proven implementation based on a surface charge
transfer acquisition principle. It consists of charging the electrode capacitance and then
transferring a part of the accumulated charges into a sampling capacitor until the voltage
across this capacitor has reached a specific threshold. In the high density and medium+
density STM8L15xx devices, the acquisition sequence is managed by software and it
involves analog I/O groups and the routing interface.
Reliable touch sensing solution can be quickly and easily implemented using the free STM8
touch sensing firmware library.
Timers
The high density and medium+ density STM8L15xx devices contain one advanced control
timer (TIM1), three 16-bit general purpose timers (TIM2,TIM3 and TIM5) and one 8-bit basic
timer (TIM4).
All the timers can be served by DMA1.
