26.2 Operation
The regulator of this product always operates in any mode (normal operation mode, HALT mode, IDLE1 mode, IDLE2
mode, STOP mode, or during reset).
Be sure to connect a capacitor (4.7
μ F (recommended value)) to the REGC pin to stabilize the regulator output.
A diagram of the regulator pin connection method is shown below.
