7.2.2 WDT Configuration Register (60h)

Offset:

 

60-61h

Default Value:

00h

Size:

 

16 bits

Attribute:

R/W

 

 

 

 

Bit

 

Description

 

 

 

 

 

15-6

 

Reserved

 

5WDT_OUTPUT: Output Enable

This bit indicates whether or not the WDT will toggle the WDT_TOUT# pin if the WDT times out.

4-3

Reserved

2WDT_PRE_SEL: Prescaler Select

The WDT provides two options for prescaling the main down counter. The preload values are loaded into the main down counter right justified. The prescaler adjusts the starting point of the 35 bit down counter.

0 – The 20 bit preload value is loaded into bits 34:15 of the main down counter. The resulting timer clock is PCI clock (33MHz) divided by 215. The approximate clock generated 1KHz.(1ms to 10 min)

1 – The 20 bit preload value is loaded into bits 24:15 of the main down counter. The resulting timer clock is PCI clock (33MHz) divided by 25. The approximate clock generated 1MHz.(1µs to 1sec)

1-0WDT_INT_TYPE

The desired type of interrupt if the WDT reaches the end of the first stage without being reloaded.

00 = IRQ (APIC 1, IRQ 10)

01 = Reserved

10 = SMI

11 = Disabled

7.2.3 WDT Lock Register (68h)

Offset:

68h

Default Value:

00h

Size:

8 bits

Attribute:
