Measurement Core Module (incl. ADC2)
23.1
Features
• 8 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 statuses for all channel thresholds
23.2
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 consists of
ten identical channel units attached to the outputs of the 10-channel 8-bit ADC (ADC2). It processes ten channels,
where the channel sequence and prioritization is programmable within a wide range.
