LC78622NE
TJ commands
When the LC78622NE 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 LC78622NE 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 microprocessor issued commands. However, this function is only valid when disk motor
control is in CLV mode.
