6.9.2 Brownout, Supply Voltage Supervisor (SVS)

The brownout circuit provides the proper internal reset signal to the device during power-on and power-off. The SVS circuitry detects if the supply voltage drops below a user-selectable level and supports both supply voltage supervision (the device is automatically reset) and supply voltage monitoring (the device is not automatically reset).

The CPU begins code execution after the brownout circuit releases the device reset. However, VCC may not have ramped to VCC(min) at that time. The user must make sure the default FLL+ settings are not changed until VCC reaches VCC(min). If desired, the SVS circuit can be used to determine when VCC reaches VCC(min).
