= 0 Disable 
= 1 Enable 

Bit 1-0 : Reserved 
 
CRF6 (Default 0x00) 
Watch Dog Timer Time-out value. Writing a non-zero value to this register causes the counter 
toload the value to Watch Dog Counter and start counting down. If the Bit 7 and Bit 6 are set, 
anyMouse Interrupt or Keyboard Interrupt event will also cause the reload of previously-loaded 
non-zerovalue to Watch Dog Counter and start counting down. Reading this register returns 
current value inWatch Dog Counter instead of Watch Dog Timer Time-out value. 
 
Bit 7 - 0 = 0x00 Time-out Disable 

= 0x01 Time-out occurs after 1 second/minute 
= 0x02 Time-out occurs after 2 second/minutes 
= 0x03 Time-out occurs after 3 second/minutes 
= 0xFF Time-out occurs after 255 second/minutes 

 
CRF7 (Default 0x00) 
Bit 7 : Mouse interrupt reset Enable or Disable 

= 1 Watch Dog Timer is reset upon a Mouse interrupt 
= 0 Watch Dog Timer is not affected by Mouse interrupt 

Bit 6 : Keyboard interrupt reset Enable or Disable 

= 1 Watch Dog Timer is reset upon a Keyboard interrupt 
= 0 Watch Dog Timer is not affected by Keyboard interrupt 

Bit 5 : Force Watch Dog Timer Time-out, Write only 

= 1 Force Watch Dog Timer time-out event; this bit is self-clearing. 

Bit 4 : Watch Dog Timer Status, R/W 

= 1 Watch Dog Timer time-out occurred 
= 0 Watch Dog Timer counting 

Bit 3 -0 : These bits select IRQ resource for Watch Dog. Setting of 2 selects SMI.
