Watchdog Timer Refresh
Watchdog Timer Timeout Response
When first enabled, the WDT is loaded with the value in the WDT Reload registers. The
WDT then counts down to
Execution of the
Reload value stored in the WDT Reload registers. Counting resumes following the reload
operation.
When Z8 Encore! is operating in DEBUG Mode (through the OCD), the WDT is
continuously refreshed to prevent unnecessary WDT timeouts.
The WDT times out when the counter reaches
either a system exception or a Reset. The
response of the WDT. For information on programming of the
Flash Option Bits
WDT System Exception in Normal Operation
If configured to generate a system exception when a timeout occurs, the WDT issues an
exception request to the interrupt controller. The eZ8 CPU responds to the request by
fetching the System Exception vector and executing code from the vector address. After
timeout and system exception generation, the WDT is reloaded automatically and
continues counting.
WDT System Exception in STOP Mode
The WDT automatically initiates a Stop Mode Recovery and generates a system exception
request if configured to generate a system exception when a timeout occurs and
the Z8 Encore! XP F1680 Series is in STOP mode. Both
the Reset Status register are set to 1 following WDT timeout in STOP mode.
Following completion of the Stop Mode Recovery the eZ8 CPU responds to the system
exception request by fetching the System Exception vector and executing code from the
vector address.
WDT Reset in Normal Operation
The WDT forces the device into the Reset state if configured to generate a Reset when a
timeout occurs. The WDT status bit is set to 1, see
more information on Reset and the
Low-Voltage Detection
initialized with its reset value.
