2.1.5

Clock

The high-speed internal (HSI) 16 MHz oscillator is selected as clock source for the low-

power demonstration software. The application manages the peripheral clocks depending

on the selected power-saving mode. When the device enters low-power run mode, the HSI

is switched OFF and the LSI acts as the main clock source until the device is woken-up by

an external event. See Section 1.6: Low-power modes for clock management information

during low-power sequences.

2.2

STM8Lx standard firmware library configuration

There are no particular settings for the stm8l15x_conf.h configuration file. All peripheral

functions are enabled by default.
