5.2.2.5 Brown-Out Reset (BOR)
The microcontroller provides a brown-out detection circuit that triggers if the V
DD
(external) or V
DDA
(analog) power supply drops below its corresponding brown-out threshold voltage. If a brown-out
condition is detected, the system may generate an interrupt, a system reset or a Power-On Reset.
The default value at reset is to generate an interrupt.
