3* Track Jump
This CD player is doing track jumps of 1, 10,
50, 100 via the auto sequence of CXA1082AS.
The auto sequence sends the timing data from
the system jU-COM to the RAM of CXA1082AS
beforehand. Therefore just by sending the serial
data of the auto sequence, the TRACK JUMP
and FOCS are drawn in.
Figures a. to d. show the timing charts of the 1,
10, 50, or 100 track jump and auto sequence.
The time control in the figures is done by
setting $5X with the system JU-COM.
Auto sequence starts by the sending of $4X in
the table below.
