WDT counter interval cannot be longer than the preset time, otherwise, WDT   sends a
reset signal to the system.

The following is an example of

 

clearing the WDT program

 

in Intel 8086 assembly

language.

      

; ( Clear the WDT)

   Mov    dx,  F2h    ;Setting the WDT configuration port
   In      al,   dx

     

Note:

  Before running WDT, you must clear WDT to ensure

                that the initial value is zero.

B.3.3 WDT Control Register

             

Note:

  This register writes to WDT configuration port.

Set WDT Control Register to control the WDT working mode.  The initial value of
WDT Control Register is shown as follows:

 

       ; (Setting the WDT Control Register as AL)

           Mov

    al, 0h  ; Setting initial value = 0 for the WDT Control Register

Follow these instructions to set the register:

1.

Select the time-out intervals of WDT (decide the values of D2, D1, D0 in F2 )

      

Example

: If D2~D0 = 0, the time-out interval is 64 seconds.

               AND        al, 11111000b  ; Setting the time-out interval as 64 sec.

2.

Enable or Disable WDT ( decide D3 value in F2)

i.e. D3=0, Disables WDT

B.3.2 Clear the WDT

           

AND      al, 11110111b  ; Disable the WDT
