Power saving modes
In this mode, the oscillator frequency is divided by 32. The CPU and peripherals are clocked
at this lower frequency.
Note:
Slow Wait mode is activated when entering Wait mode while the device is already in Slow
mode.

Wait mode
Wait mode places the MCU in a low power consumption mode by stopping the CPU.
This power saving mode is selected by calling the ‘WFI’ instruction.
All peripherals remain active. During Wait mode, the I bit of the CC register is cleared, to
enable all interrupts. All other registers and memory remain unchanged. The MCU remains
in Wait mode until an interrupt or RESET occurs, whereupon the Program Counter branches
to the starting address of the interrupt or Reset service routine.
The MCU will remain in Wait mode until a Reset or an Interrupt occurs, causing it to wake
up.
