Guys,

What should I do if T0IF =3D 0 ? nop ?

counting     btfss  INTCON,T0IF         ;is timer0 interrupt flag true ?
*            nop**
*                     bcf     INTCON,T0IF            ;if T0IF=3Dfalse=20
clear timer0 interrupt flag
                       decf    LedTimer,1          ;if T0IF=3Dtrue reduce=20
the counter
                      ;check if LedTimer =3D 0 ?
                      btfsc     STATUS, Z             ;Z bit is set to 1=20
if W was 00 - skip next instruction if not 00
                       ;LedTimer=3D0
                      goto   next_state          ;from btfsc if it's 1,=20
go to next state
                      ;LedTimer!=3D0
                       goto   counting            ;from btfsc if it's 0=20
keep counting interrupt

         next_state    incf    LedState,1            ; if 00 increase=20
the state, for the next state
                            return
