When the LC78624E receives a track jump instruction as a servo command, it first generates accelerating pulses
(period a) and next generates deceleration pulses (period b). The passage of the braking period (period c) completes
the specified jump. During the braking period, the LC78624E detects the beam slip direction from the TES and
HFL inputs. TOFF is used to cut the components in the TES signal that aggravate slip. The jump destination track
is captured by increasing the servo gain with TGL. In during TOFF output mode JP pulse period the TOFF signal
is held high during the JP pulse generation period.
Note: Of the modes related to disk motor control, the TOFF pin only goes low in CLV mode, and will be high
during accelerate, stop, and decelerate modes.Note that the TOFF pin can be turned on and off independently
by microcontroller issued commands. However, this function is valid only when disk motor control is in
CLV mode.
