Tracking brake
The chart shows the relationships between the TES, HFL, and TOFF signals during the track jump C period. The TOFF signal is extracted from the
HFL signal by TES signal edges. When the HFL signal is high, the pickup is over the mirror surface, and when low, the pickup is over data bits.
Thus braking is applied based on the TOFF signal being high when the pickup is moving from a mirror region to a data region and being low when
the pickup is moving from a data region to a mirror region.
JP three-value output
The JP three-value output command allows the track jump operation to be controlled from a single pin.
Track check mode
The LC78622E will count the specified number of tracks minus one when the microprocessor sends an arbitrary
binary value in the range 8 to 254 after issuing either a track check in or a track check out command.
