MICROCONTROLLER WRITE OPERATION SEQUENCE (REPEAT
MODE
)
The same command can be repeated several times (e.g.
for fade function) by applying APP2 pulses as shown in
Fig.4. It should be noted that APP1 must stay HIGH
between APP2 pulses. A minimum pause of 22
s is
necessary between any two step-up or step-down
commands.
