Description

This block configures the counter reset source of the watchdog module on the processor. The watchdog module, after configuration, resets the system if not serviced periodically.

Ports

Input

Input — Resets watchdog counter

scalar

When the input signal is 1, the counter is reset.

Dependencies

This parameter appears only when Watchdog counter reset source is set to Input port.

Data Types: int8 | uint8 | int16 | uint16 | int32 | uint32 | single | double | Boolean

Parameters

Watchdog counter reset source — Watchdog counter reset source

Specify via dialog (default) | Input port

The watchdog counter reset source.

• Input — Create an input port on the watchdog block. When the input signal is 1, the counter is reset.

• Specify via dialog — The watchdog timer is reset based on the Sample time value.

Sample time — Frequency at which processor resets Watchdog timer

–1 (default) | scalar

Sample time for the block in seconds. To execute this block asynchronously, set this parameter to -1.

Dependencies

This parameter appears only when Watchdog counter reset source is set to Specify via dialog.
