This command is used to set N when a 2N TRACK JUMP and an N TRACK MOVE are executed for auto
sequence.
• The maximum track count is 65,535, but note that with 2N track jumps the maximum track jump count is
determined by the mechanical limitations of the optical system.
• The number of track jump is counted according to the signals input from CNIN pin.
