Peak value set ($3X)
This command is used for the peak value setting of focus search and sled kick.
D0, D1: Sled kick
D2, D3: Focus search peak value
Auto Sequencer command ($4X)
This command is used for reducing control time and replacing several command by one auto- sequence command.
Auto sequencer mode is performed from the first falling edge of WDCK clock after the falling of the latch pulse.
Auto sequencer does not carry out tracking gain up, brake, anti-shock and focus gain down.
MICOM checks ISTAT pin (/BUSY) and sends to $40 command to reset preceding auto sequencer status
