Continuous Read/Write
Once the conversion cycle is concluded, the LTC2493 can
be written to and then read from using the Repeated Start
(Sr) command.
Figure 8 shows a cycle which begins with a data Write, a
repeated Start, followed by a Read and concluded with a
Stop command. The following conversion begins after all
32 bits are read out of the device or after a Stop command.
The following conversion will be performed using the
newly programmed data. In cases where the same speed
(1x/2x mode) and rejection frequency (50Hz, 60Hz, 50Hz
and 60Hz) is used but the channel is changed, a Stop or
Repeated Start may be issued after the first byte (channel
selection data) is written into the device.
Discarding a Conversion Result and Initiating a New
Conversion with Optional Write
At the conclusion of a conversion cycle, a write cycle
can be initiated. Once the write cycle is acknowledged, a
Stop command will start a new conversion. If a new input
channel or conversion configuration is required, this data
can be written into the device and a Stop command will
initiate the next conversion (see Figure 9).
