Notes Concerning Microprocessor Program Creation
1.
Commands
After sending the FOCUS START command and the E/F BALANCE START command, send 11111110 (FEH) in order to
clear the internal registers of the IC.
Reason: Although the above commands are executed at point
1
in the timing chart below, the same commands will be
executed again at point
2
if there is subsequent input to CE as shown below.
When sending a TRACK-OFFSET ADJUST START command or a FOCUS-OFFSET ADJUST START command after either
V
CC
ON (POWER ON RESET), RESET command, or a corresponding OFFSET ADJUST OFF command, waiting time is
necessary as listed below. (Only when a 4.2 MHz clock is input.)
TRACK-OFFSET ADJUST START: 4 ms or more
FOCUS-OFFSET ADJUST START: 4 ms or more
2.
E/F balance adjustment
E/F balance adjustments should be made in a bit region of the disc, not a mirrored region.
Since there is no track-kick for LA9240M, measures must be taken during EF balance adjustment to obtain a stable TE
signal. (By a sled movement signal from a microprocessor, for example.)
Timing
2 μs or more
1 μs or more
10 μs or more
1 μs or more
2 μs or more
