Figure 5. Power-On Reset Operation
Voltage Brownout Reset
The devices in the Z8 Encore! XP F0823 Series provide low VBO 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 POR voltage threshold (V
), the VBO block holds the device in the Reset.
POR
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 POR section.
Following POR, the POR status bit in the Reset Status (RSTSTAT) register is set to 1.
Figure 6
displays Voltage Brownout operation. For the VBO and POR threshold
voltages (V
and V
), see
Electrical Characteristics
on page 193.

The VBO circuit can be either enabled or disabled during STOP mode. Operation during
STOP mode is set by the VBO_AO Flash Option bit. For information on configuring
VBO_AO, see
