AN5757S - CRT horizontal deflection voltage controller
MICROCONTROLLERS Aug 10, 2001 App Note 101: Using the Secure Microcontroller Watchdog Timer The Secure Microcontroller Family (DS5000FP, DS5001FP, DS5002FP, and associated modules) integrate an internal watchdog timer to prevent code execution errors.
The watchdog timer uses the high precision crystal oscillator that is also used by the microcontroller.
This eliminates the need for a RC oscillator while providing greater accuracy.

AN5757S Features
* and use of the Secure Microcontroller’s watchdog timer. General Use of a Watchdog Timer The primary application of a watchdog timer is as a system monitor to detect and reset an "out of control" microprocessor. When program execution goes awry it will not properly execute the code that restarts th
