Brown-out Detection Watchdog Reset The watchdog’s function can be enabled at the WDC register and triggers a reset with every watchdog counter overflow. To suppress the watchdog reset, the watchdog counter must be regularly reset by reading the watchdog register address (CWD). The CPU reacts in exactly the same manner as a reset stimulus from any of the above sources. External Clock Supervisor The external input clock supervisor function can be enabled if the external input clock is selected within the CM and SC registers of the clock module. The CPU reacts in exactly the same manner as a reset stimulus from any of the above sources. Voltage Monitor The voltage monitor consists of a comparator with internal voltage reference. It is used to supervise the supply voltage or an external voltage at the VMI pin. The comparator for the supply voltage has three internal programmable thresholds one lower threshold (2.2 V), one middle threshold (2.6 V). and one higher threshold (3.0 V). For external voltages at the VMI pin, the comparator threshold is set to V BG = 1.3 V. The VMS bit indicates if the supervised voltage is below (VMS = 0) or above (VMS = 1) this thresh- old. An interrupt can be generated when the VMS bit is set or reset to detect a rising or falling slope. A voltage monitor interrupt (INT7) is enabled when the interrupt mask bit (VIM) is reset in the VMC register.
