3. CNTL-L, U ($BX, $CX)

When the number of tracks to be counted is input from MICOM, the CNTL-L, or CNTL-U register

loads the data into the tracking counter. This tracking counter is used for improving track jump

characteristics.

When the number of tracks to be jumped is input from MICOM, the track number is loaded from

MLTs positive edge to the register. If CNTL-L is selected, /COMPLETE signal is output to the

/ISTAT pin, and if CNTL-U is selected, /COUNT signal is output. The Timing Diagrams of the

tracking counters are Figure-2 and Figure-3.
