Message Format for Writing
Write to the devices by transmitting the device’s slave
address with NOP/W (eighth bit) set to zero, followed by
at least 2 bytes of information. The first byte of informa-
tion is the command byte. The second byte is the data
byte. The data byte goes into the internal register of the
device as selected by the command byte (Figure 7 and
Table 2).
Command Byte
Use the command byte to select the destination of the
wiper data. See Table 2.
Command Descriptions
REG A: The data byte writes to register A and the wiper
of potentiometer A moves to the appropriate position.
D[7:0] indicates the position of the wiper. D[7:0] = 00h
moves the wiper to the position closest to LA. D[7:0] =
FFh moves the wiper to the position closest to HA. D[7:0]
is 80h following power-on.
