26.3.3 Single mode
This mode activate comparator as specified and generate interrupt by compare result, and deactivate comparator
automatically by hardware.
Setting instruction:
(1) Set Operating clock, filtering, interrupt option, and single mode by CMPnMOD register.
CMPnE1-0
Description
00
Generate interrupt when CMPnD is ”0”
01
10
Generate interrupt when CMPnD is ”1”
11
(2) Set CMPnEN
(3) After Trdy progress, CMPnRF is set to ”1”, and then data is set to CMPnD. At that time, if the condition that
was set by CMPnE1-0 match, generate interrupt.
(4) After Tend progress, hardware set CMPnEN to “0”. CMPnD compare result is kept until CMPnEN is set
to ”1”.
Need interval (Trdy+Tend) of from CMPnEN setting to next MPnEN setting. It is recommended to confirm
CMPnEN=”0” before set CMPnEN.
It is prohibited to switch to STOP mode during operation. CMPnEN need to be set “0” when switch to STOP
mode.
