DAC can be served by DMA1.
Ultralow power comparators
The medium density STM8L15x embeds two comparators (COMP1 and COMP2) sharing
the same current bias and voltage reference. The voltage reference can be internal or
external (coming from an I/O).

The two comparators can be used together to offer a window function. They can wake up
from Halt mode.
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, DAC and the internal reference voltage V
it provides a set of registers for efficiently managing a set of dedicated I/Os supporting up to
16 capacitive sensing channels using the ProxSense
Timers
Medium density STM8L15x 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.
