Reset, Stop Mode Recovery, and
Low-Voltage Detection
Overview
Reset Types
PS025011-1010
The Reset Controller within the Z8 Encore! XP F1680 Series device controls Reset and
Stop Mode Recovery operation and provides indication of low-voltage supply conditions.
During the operation, the following events cause a Reset:
When the device is in STOP mode, a Stop Mode Recovery is initiated by each of the
following:
The low-voltage detection circuitry on the device features the following:
The Z8 Encore! XP F1680 Series provides various types of Reset operation. Stop Mode
Recovery is considered a form of Reset.
their operating characteristics. The System Reset is longer, if the external crystal oscillator
is enabled by the Flash option bits allowing additional time for oscillator start-up.
