5.3.2 Control Mode Selection
Thecontrolmodedeterminesthemethodusedtocontrolscanningofthelightscreen
array(seeFigure5-11).Choosefromthreemaincontrolmodes:
• ContinuousScanmode,
• SerialHostCommandmode,and
• Gatemode(whichitselfhasfouroptions)
In Continuous Scan Mode,thecontrolmodulebeginsanewscanassoonasit
updatestheoutputsfromthepreviousscan.Thisisthefastestscancontrolmethod;it
isusedinmostanalogoutputapplicationsandwhenevercontinuousupdatingofthe
