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 µs is

necessary between any two step-up or step-down

commands.
