An ON pulse across the System Shutdown Request bit will stop the sequence and turn the System On bit OFF,
making the system inactive.
A toggle OFF followed by a toggle ON of the System Enabled Request bit will put the system back into the active
state after the EFR has shut down.
The Sequence Data must be read before the EFR
finishes running another sequence. If the Sequence
Data is not read before finishing the sequence, the data
will be overwritten with new Sequence Data.
The Sequence Data consists of:
•
Total Sequence Amount Requested

Total Sequence Amount Dispensed
•
Sequence Start Outlet Pressure for Red Pump
•
Sequence Start Outlet Pressure for Blue Pump
•
Sequence End Outlet Pressure for Red Pump
