Chapter 26 Analog Comparator
FEUL620Q504 26–9
26.3.4 Single monitor mode
This mode activate comparator as specified and generate interrupt after measurment, and deactivate comparator
automatically by hardware.
Setting instruction:
(1)Set operation clock, filtering, and single monitor mode by CMPnMOD register.
Interrupt stting is invalid. Only complete interrupt is generated. Also complete interrupt is generated in case
of suspend of operation by software.
(2) Set CMPnEN
(3) After Tend progress, comparator is automatically off and generate complete interrupt. Read
CMPnD(Compare result) from software. CMPnD (Compare result) is kept until “1” is set to CMPnEN.
It is prohibited switch to STOP mode during operation. CMPnEN need to be “0” when switch to STOP mode.
The timing chart is as follows
Figure 26-4 Timing in the single-monitor mode
Time before CMPnD setting becoming valid is depending on operation/sampling clock setting.
