2-BYTE MODE
The 2-byte mode lets the user update channels sequentially
following initialization of this mode. The device address byte is
required only once and the address pointer is configured for
autoincrement or burst mode.
The user must begin 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 a specific
pointer byte (0xFF), which initiates the burst mode of opera-
tion. The address pointer initializes to Channel 0 and the data
following the pointer is loaded to Channel 0. The address
pointer automatically increments to the next address.
The REG0 and REG1 bits in the data byte determine the register
to be updated. In this mode, following the initialization, only
the two data bytes are required to update a channel. The
channel address automatically increments from Address 0 to
the final address and then returns to the normal 3-byte mode
of operation. This mode allows transmission of data to all
channels in one block and reduces the software overhead in
configuring all channels. A STOP condition at any time exits
this mode. Toggle mode of operation is not supported in
2-byte mode. Figure 36 shows a typical configuration.
