Adds the acceleration rate to the
current frequency to change
frequency whenever CTC2 turns
ON while acceleration flag 1200 is
ON. When the current frequency
reaches fH, stops acceleration and
sets the deceleration pulse count.
Subtracts the acceleration rate from
the current frequency to change
frequency whenever CTC2 turns
ON while acceleration flag 1200 is
OFF. When the current frequency
reaches fL, stops deceleration and
initializes the settings.
When pulse count of clock pulses
equals the setting value of CTC3,
stops clock pulse output.
