 LDA value4             ; Set the music counter to value4, so we introduce a
 STA counter            ; rest of value4 interrupts (i.e. a pause where we play
                        ; no music)

 JMP BDirqhere          ; Jump back to the start of the interrupt routine so the
                        ; counter starts to count down
