Features
• 7 individually programmable channels split into two groups of user configurable and non user
configurable
• Individually programmable channel prioritization scheme for measurement unit
• Two independent filter stages with programmable low-pass and time filter characteristics for each
channel
• Two channel configurations:
– Programmable upper- and lower trigger thresholds comprising a fully programmable hysteresis
– Two individually programmable trigger thresholds with limit hysteresis settings
• Individually programmable interrupts and status for all channel thresholds
• Operation down to reset threshold of entire system

Introduction
The basic function of this block is the digital postprocessing of several analog digitized measurement signals
by means of filtering level comparison and interrupt generation. The measurement postprocessing block is
built of seven identical channel units attached to the outputs of the 7-channel 8-bit ADC (ADC2). It processes
seven channels, where the channel sequence and prioritization is programmable within a wide range.
