VBO
The devices in the Z8 Encore! F083A Series provide low VBO protection. The VBO
circuit forces the device to the Reset state, when the supply voltage drops below the VBO
threshold voltage (unsafe level). While the supply voltage remains below the POR
threshold voltage (V
After the supply voltage exceeds the POR threshold voltage, 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.

Electrical Characteristics
The POR level is greater than the VBO level by the specified hysteresis value. This
ensures that the device undergoes a POR after recovering from a VBO condition.
The VBO circuit is either enabled or disabled during STOP mode. Operations during
