Note: 1. If focus is lost during the execution of an internal brake command, the pickup must first be refocussed
and then the internal brake command must be reissued.
2. Since incorrect deceleration state determination is possible depending on the EFM signal playback state
(e.g., disk defects, access in progress), we recommend using these functions in combination with a
microprocessor.

The LC78622NE supports the two track count modes listed below.
The earlier track count function uses the TES signal directly as the internal track counter clock.
To reduce counting errors resulting from noise on the rising and falling edges of the TES signal, the new track
count function prevents noise induced errors by using the combination of the TES and HFL signals, and
implements a more reliable track count function. However, dirt and scratches on the disk can result in HFL signal
dropouts that may result in missing track count pulses. Thus care is required when using this function.
