System and Reset Characteristics
Note:
1. The Power-on Reset will not work unless the supply voltage has been below VPOT (falling)
Note:
1. V
BOT 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 guarantees that a Brown-out Reset will occur before VCC drops to
a voltage where correct operation of the microcontroller is no longer guaranteed.
