Appendix A Programming the Watchdog Timer

 

A-4

 

WatchDog Timer Configuration Registers 

 

Configure Control (Index=02h) 

This register is write only. Its values are not sticky; that is to say, a 
hardware reset will automatically clear the bits, and does not 
require the software to clear them.
