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 the CNIN pin.
