{{fname|pyb.wfi()}} is used to reduce power consumption while waiting for an event such as an interrupt. You would use it in the following situation:
<nowiki>while True:
do_some_processing()
pyb.wfi()</nowiki>
Control the frequency using {{fname|pyb.freq()}}:
<nowiki>pyb.freq(30000000) # fixer la fréquence du CPU à 30MHz</nowiki>
