Appendix C - Sequence Step Data Exchange

Appendix C - Sequence Step Data Exchange
The Sequence Data Exchange is a condensed structure used to read and edit a number of steps in a sequence
across a set of bytes. If multiple steps of sequences are needed, they must be cycled through.
Below is a timing diagram showing the Sequence Step Data Exchange portion of EFR CGM Map.
NOTE: A 50ms delay is suggested between each CGM signal.
When utilizing the Sequence Step Data Exchange, the first element that must be passed to the EFR is the Desired
Step of the Active Sequence. Once the EFR receives that element, the EFR will update the Sequence Step Data
Exchange Automation Inputs Elements for the desired step. After the Sequence Step Data Exchange Automation
Inputs Elements have been updated, the Selected Step of the Active Sequence can be used to confirm the desired
step data has populated the Sequence Step Data Exchange Automation Inputs Elements. Once the data has been
confirmed for the desired step, the Sequence Step Data Exchange Automation Outputs Elements can be used to
request new values to the EFR. If the values supplied are within the operable range of the elements, the EFR will
accept the values and reflect the new values to the corresponding elements of the Sequence Step Data Exchange
Automation Inputs Elements.
