18.5 System and Reset Characteristics
Note:
1. The Power-on Reset will not work unless the supply voltage has been below VPOT (falling)
18.5.1
Brown-Out Detection
Note:
1. VBOT may be below nominal minimum operating voltage for some devices. For devices where
this is the case, the device is tested down to VCC = VBOT during the production test. This guar-
antees that a Brown-out Reset will occur before VCC drops to a voltage where correct
operation of the microcontroller is no longer guaranteed.
18.6 Analog Comparator Characteristics
Note:
All parameters are based on simulation results and they are not tested in production
