The state of these bits must match the state of pins A3 and A2 in order for a proper
DAC5573 data update, except in broadcast update mode.
Are used for selecting the update mode.
Store I
2
C data. The contents of MS-BYTE and LS-BYTE (or power down information) are stored in the
temporary register of a selected channel. This mode does not change the DAC output of the selected
channel.
Update selected DAC with I
2
C data. Most commonly utilized mode. The contents of MS-BYTE and
LS-BYTE (or power down information) are stored in the temporary register and in the DAC register of
the selected channel. This mode changes the DAC output of the selected channel with the new data.
4-channel synchronous update. The contents of MS-BYTE and LS-BYTE (or power down information)
are stored in the temporary register and in the DAC register of the selected channel. Simultaneously,
the other three channels get updated with previously stored data from the temporary register. This
mode updates all four channels together.
Broadcast update mode. This mode has two functions. In broadcast mode, DAC5573 responds
regardless of local address matching, and channel selection becomes irrelevant as all channels update.
This mode is intended to enable up to 64 channels simultaneous update, if used with the I
2
C broadcast
address (1001 0000).
If Sel1=0
All four channels are updated with the contents of their temporary register data.
If Sel1=1
All four channels are updated with the MS-BYTE and LS-BYTE data or powerdown.
