Function procedure
1. If the value at CMP1−IN1 exceeds the value at CMP1−IN2, CMP1−OUT changes from LOW to
HIGH.
2. If the value at CMP1−IN1 undershoots the value at CMP1−IN2 minus C0681 again, CMP1−OUT
changes from HIGH to LOW.

Function procedure
1. If the value at CMP1−IN1 falls below the value at CMP1−IN2, CMP1−OUT changes from LOW
to HIGH.
2. If the value at CMP1−IN1 exceeds the value at CMP1−IN2 plus C0681 again, CMP1−OUT
changes from HIGH to LOW.
