Rev. E | Page 29 of 44
3-BYTE MODE
The 3-byte mode lets the user update more than one channel in
a write sequence without having to write the device address byte
each time. The device address byte is required only once and
subsequent channel updates require the pointer byte and the
data bytes. In 3-byte mode, the user begins with an address byte
(R/W = 0) after which the DAC acknowledges that it is prepared
to receive data by pulling SDA low. The address byte is followed
by the pointer byte; this addresses the specific channel in the
DAC to be addressed and is also acknowledged by the DAC.
Address Bits A3 to A0 address all channels on the
AD5390/AD5391. Address Bits A2 to A0 address all channels
on the AD5392. Address Bit A3 is a zero on the AD5392. This is
then followed by the two data bytes. REG1 and REG0 determine
the register to be updated.
If a STOP condition is not sent following the data bytes,
another channel can be updated by sending a new pointer
byte followed by the data bytes. This mode requires only three
bytes to be sent to update any channel once the device has
been initially addressed and reduces the software overhead in
updating the AD539x channels. A STOP condition at any time
exits this mode. Figure 35 shows a typical configuration.
