Answer #1

for using DECFSZ filereg F

for back functions BNZ back

program:

count  EQU 0x25 //clear the WREG

MOVLW D'10' // move value 10 to D register

MOVLW count // store the count

MOVLW 0 // after store and set to be 0

again ADDLW 3 // naming for loop is again

DECF count,F // for using DECF loop

BNZ again // back to again loop for ten times

MOVWF PORTB //store it to the port b for results in SFR
