Example of Connection and System Application
Figure 3.24.3 shows an example of the external circuit using this system.
The power management pin (PWE) controls the power supply to circuits and pins. In
In the Power Cut Mode, the PWE pin outputs “Low” to cut off the power to most part of
The Power Cut Mode is released by a wake-up request. Then, the PWE pin outputs
