■ Changing the CMP setting value
Compares the current value of C000 to the CMP setting value. Sets the CMP setting
value to analog timer TMIN0.
The following example changes the setting value within the range from 0 to 100.
Turns ON 0500 when the C000 value is smaller than the CMP setting value.
Turns ON 0501 when the C000 value is greater than the CMP setting value.

■ Multi-level comparator
Compares the counter current value according to the following range:
•
0 to 999 → 0500 turns ON.
• 1000 to 1999 → 0501 turns ON.
• 2000 to 2999 → 0502 turns ON.
