Is the reloading of '00000000' needed? Can't you load it once and than send it to each port needed? Would the code act the same if all the "movlw b'00000000'" lines are deleted after the first one?

"; INITIALISE PORTS
; binary used to see individual pin level

movlw b'00000000' ; all port pins = low
movwf PORTA
movlw b'00000000'
movwf PORTB
movlw b'00000000'
movwf PORTC
movlw b'00000000'
movwf PORTD
movlw b'00000000'
movwf PORTE

    Hi, I am going to use a 16F84A as an ignition coil driver (8 coils, 1/Cyl) I need to react to the trigger pulse from the ECU and drive the relevant coil on but I also want to use an interrupt on RB0 to measure the time period in uSecs between the 60 deg and 30 deg crank triggers. This period will give me a 30 degree dwell period so I can multi spark the relevant coil. I am somewhat lost though how to do this. Can you please help? Ivan
