NVIC

Some basic NVIC APIs are provided by the STM32W108xx standard library drivers to

manage the NVIC registers. These NVIC APIs are summarized in the following table:

3.3.3

CLK

In addition to the basic clock API provided by the STM32W108xx standard library drivers,

the required functions to calibrate the internal clocks HSI and LSI are added. The following

table provides an overview of the CLK changes.
