CYCLICAL DATA
EVENT n
(Data at Which Fault Occurred; Most Recent Data)
Event “n” represents one complete cycle of ADC reads through the MUX
at time of fault. Example: If the fault occurs when the ADC is processing
step 15, it will continue to take readings through step 25 and then store
the header and all 6 event pages to
EEPROM
