System and Reset Characteristics
Note:
1. When RESET pin used as reset (not as I/O).
2. Not tested in production.
18.5.1
Enhanced Power-On Reset
Note:
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 VPOA.
18.5.2
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 V
CC drops to a voltage where correct
operation of the microcontroller is no longer guaranteed.
