Power control
=============
:meth:`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::
while True:
do_some_processing()
pyb.wfi()
Control the frequency using :meth:`pyb.freq`::
pyb.freq(30000000) # set CPU frequency to 30MHz
