protection. The VBO circuit senses when the supply voltage drops to an unsafe level
(below the VBO threshold voltage) and forces the device into the Reset state. While the
supply voltage remains below the Power-On Reset voltage threshold (V
block holds the device in the Reset.
After the supply voltage again exceeds the Power-On Reset voltage threshold, the device
progresses through a full System Reset sequence, as described in the Power-On Reset sec-
tion. Following Power-On Reset, the POR status bit in the Reset Status (RSTSTAT) regis-
ter is set to 1. Figure 6 illustrates Voltage Brown-Out operation. Refer to the chapter
“Electrical Characteristics” on page 176 for the VBO and POR threshold voltages (V

The Voltage Brown-Out circuit can be either enabled or disabled during STOP mode.
Operation during STOP mode is set by the VBO_AO Flash Option Bit. Refer to the Flash
