Comparison Output Function

8.1 Comparison Output Function

8.1.1 Overview of Comparison Output Function

• The comparison output function is used for comparing the "counter elapsed value by
external input" or "pulse output counter elapsed value of pulse output/PWM output" to an
arbitrary "comparison output setting value" and outputting the comparison result.
• There are eight points for the comparison result output [CMPx], and the types and channels
of compared counters, and the comparison condition can be arbitrarily allocated by the
software. Also, all comparison output setting values are set to the same counter, and it can
be used as a counter with a maximum of eight steps.
• The conditions of the comparison output are selectable from "ON when elapsed value is
larger than or equal to setting value" and "ON when elapsed value is smaller than setting
value".
