Tracking servo offset control command

(-160mV
+160mV)
Control window is used with the balance window and monitors the
ISTAT output
Because tracking offset of approximately +30mV - +50mV is ideal
in the system, consider the control setting by raising to ($8F1F
$8F00) 3 - 5 steps after controlling the offset to 0mV.
<Notice> Consider the measure setting by $8010 command
of tracking switch and $811F command of tracking gain
switch after $24 command.
