20.2 Operation

The regulator operates in all modes (Normal mode, HALT mode, IDLE1 mode, IDLE2 mode, STOP
mode, and during RESET).
Be sure to connect a capacitor (REGC0: 4.7 µF, REGC1: 1.0 µF) to the REGC0 and REGC1 pin to sta-
bilize the regulator output.
A diagram of the regulator pin connections is shown below.
