DIGITAL SIGNAL PROCESSOR FOR CDP
S5L986F01
TRACKING COUNTER BLOCK
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-3 and Figure-4.
