PRODUCTION DATA.
There are two alarm thresholds (high and low) per channel, with two flags for each threshold. An active alarm flag is enabled when an alarm is triggered (when data cross the alarm threshold) and remains enabled as long as the alarm condition persists. A tripped alarm flag is enabled in the same manner as an active alarm flag, but remains latched until read. Registers 11h to 14h in the program registers store the active and tripped alarm flags for all individual eight channels.
