16.3.3 Low-voltage detector (LVI)
(1) Functions
(2) Configuration
The low-voltage detector (LVI) has the following functions.
• Compares the supply voltage (V
• The level of the supply voltage to be detected can be changed in two steps.
• An interrupt request signal or internal reset signal can be selected.
• Can operate in HALT/IDLE/STOP mode.
• Operation can be stopped by software.
