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.
