Types of messages
This section gives guidelines on the basic operations to read data from and write data to
VS6724.
The serial interface supports variable length messages. A message contains no data bytes
or one data byte or many data bytes. This data can be written to or read from common or
different locations within the sensor. The range of instructions available are detailed below.
Single location, single byte data read or write.
Write no data byte. Only sets the index for a subsequent read message.
Multiple location, multiple data read or write for fast information transfers.
Any messages formats other than those specified in the following section should be
considered illegal.
3.3.1
Random location, single data write
For the master writing to the slave the R/W bit is set to zero.
The register index value written is preserved and is used by a subsequent read. The write
message is terminated with a stop condition from the master.
