Example with no command (Prepare Status & Length):
The controller may request the Status & Length of any available data anytime the sensor is in a
ACK condition. This will indicate the sensor’s readiness and the number of bytes to be read in.
Once the quantity of data is known, Header 0Ch
Read Complete Output Buffer
can be used to
read in the data. Using the Prepare Status & Length alone (without a command) is normally not
required since the number of bytes available is requested when the command is sent using
header 06h. However the status byte can be useful in some instances.
Figure 13 – Header 06h used to Prepare Status & Length
Following this command, the controller should test using ACK/NACK then read in the 4 bytes.
Prepare Status & Length will always return 4 Bytes.
