21.6.4
Cyclic Signature Generation with every incoming frame,
limiting read accesses
Cyclic for one window, with interrupt monitoring
General Configuration phase: (not shadowed registers)
Enable mask mode
Write mask window coordinates
Enable Signatures types
Enable interrupts
Configuration phase for calculation 0
Write Window 0 coordinates
Write reference values for Signature A
(Write reference values for Signature B, Set threshold for B)
Setup cyclic TriggerMode
Trigger cyclic generation by writing '1' to the trigger field
Wait on interrupt or poll IStsDiff
On IStsDiff
Read result registers Signature A, (B)
Process results
Before display content of evaluation window changes:
Cancel cyclic trigger and reprogram reference values
21.6.5

Limitation of Cyclic Signature Generation

It is not recommended to change evaluation window coordinates and relating reference values during
cyclic (= continuous) monitoring mode. Reference value registers are overtaken with every frame start.
Coordinate registers are overtaken only after write of Register TriggerW0.Trigger. If nevertheless
cyclic mode is used the following real time requirement exists for the configuration of coordinate and
reference registers: The update of coordinate and reference registers must be finished within one
video frame.
