Slow mode
This mode has two targets:
SLOW mode is controlled by three bits in the MCCSR register: the SMS bit enables or
disables SLOW mode and two CPx bits select the internal slow frequency (f
In this mode, the master clock frequency (f
and peripherals are clocked at this lower frequency (f
Slow Wait mode is activated when entering the Wait mode while the device is already in
Slow mode.

To reduce power consumption by decreasing the internal clock in the device,
To adapt the internal clock frequency (f
