CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Analog Comparator)
4.13 Analog Comparator
4.13.1 Configuration of analog comparator
The S1C60N08 Series incorporates an MOS input analog comparator. This analog comparator, which has
two differential input terminals (inverted input terminal AMPM, non-inverted input terminal AMPP),
can be used for general purposes.
Figure 4.13.1.1 shows the configuration of the analog comparator.

4.13.2 Operation of analog comparator
The analog comparator is ON when the AMPON register is "1", and compares the input levels of the
AMPP and AMPM terminals. The result of the comparison is read from the AMPDT register. It is "1"
when AMPP (+) > AMPM (-) and "0" when AMPP (+) < AMPM (-).
After the analog comparator goes ON it takes a maximum of 3 msec until the output stabilizes.
