6.16 Watchdog Timer (WDT)
OSCILLATOR
The Watchdog Timer can be used to generate a system reset if there is a CPU/software
crash. In addition the watchdog timer can be used as an ordinary timer.
how the Watchdog Timer module is connected in the system.
This module has the following features:
•
•
•
•
•
Based on the input of the Watchdog timer (see also
generate a system-wide reset in the case of a system stall.
In the event of a software or hardware failure, generates a chip-wide reset request
when its programmed time-out period has expired (output m1).
Watchdog counter can be reset by a periodical software trigger.
After a reset, a register will indicate whether a reset has occurred because of a
watchdog generated reset.
Watchdog timer can also be used as a normal timer in addition to the watchdog
functionality (output m0).
