Appendix C <Watchdog Timer Programming Guide>

                                                      WDT  source  from  :  Wi  nBond  83627HF

     (1) General Description

           

Winbond has a WDT feature inside its chip. We implement its

         function i nto our circuit .

           

There are many configuration Registors ( CR ) in 83627HF. The

        

following sequence must be followed for CR programming :

               

(*1) E nter the extended function mode

                (*2) Configure  the configuration  registers

               

(*3) E xit the extended function mode

EFER : E xtended F unction Enable Registers.( EFER=2Eh in our system )

EFIR : Extended F unction Index Register. ( Same addr. with EFER. ) EFDR :

E xtended F unction Data Register.( Located at addr.[ EF IR +1 ] )

  For instance ;

              

(*1) E nter extended function mode

                                            MOV    DX,2EH

                                            MOV      

AL,87H

                                            CLI                          ;  disable  interrupt

                                            OUT    DX,AL

                                            JMP    $+2

                                            OUT    DX,AL

                                            STI                          ;  enable  i  nterrupt

              

(*2) Configurate logical device 1 , configuration register CRF0

                                            MOV    DX,2EH

                                            MOV      

AL,07H

                                            OUT    DX,AL

; point to Logical Device Number Register

                                            MOV    DX,2FH

                                            MOV      

AL,01H

                                            OUT    DX,AL

                                            MOV    DX,2EH

                                            MOV      

AL,0F0H

                                            OUT    DX,AL

                                            MOV    DX,2FH

                                            MOV      

AL,3CH

; select logical device 1

                       OUT  DX,AL 

; update  CRF0 of LD0 with value 3C h

              

(*3) E xit extended function mode

                                            MOV    DX,2EH

                                            MOV      

AL,0AAH

                                            OUT    DX,AL
