;Call here to repeat the tone for ToneLength
;The following inits the ToneLength delay reg’s
;Low frequency tone loop timer
;result = time since last update
;Carry bit determines if enough time has elapsed
;do not update the SINE wave yet
;Very Important to add to the last reference
;instead of using the actual timer value
;update the step count
;fetch the corresponding Sin value
;store result
;High frequency tone loop timer
;result = time since last update
;Carry bit determines if enough time has elapsed
;do not update the SINE wave yet
;instead of using the actual timer value
;update the step count
