3.5.1.4 Range Comparison Function Setting
The Range Comparison setting uses Range Comparison Control Status Register (ADRCCS).
The ADRCCS Register select range comparison execution enables upper/lower threshold selection, inside/outside-
range checking, interrupt request and continuous detection count.
Upper and lower threshold values set Upper/Lower Threshold Setting Register (ADRCUT/ADRCLT).
(Please refer
to the” P18 Appendix: About the Range Comparison Operation”.)
The range comparison function setting flow shows in the following
