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
Finally, 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
AES
The AES Hardware Accelerator can be used to encipher and decipher data using the AES
algorithm (compatible with FIPS PUB 197, 2001 Nov 26).

Timers
The high density STM8L162xx 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.
