1. Values are guidelines, only.
2. Threshold where device is released from reset when voltage is rising.
3. The Power-on Reset will not work unless the supply voltage has been below V
1. V
this is the case, the device is tested down to V
antees that a Brown-out Reset will occur before V
operation of the microcontroller is no longer guaranteed.
