44.2.29 A/D Compare Function Window A Extended Input Channel Status Register
(ADCMPSER)
The ADCMPSER register stores the comparison result of the compare window A function.
CMPSTTSA Flag (Compare Window A Temperature Sensor Output Compare Flag)
This flag is a status flag that indicates the temperature sensor output comparison result. When the comparison condition
set by ADCMPLER.CMPLTSA is met at the end of A/D conversion, this flag is set to 1.
Writing 1 to the CMPSTTSA flag is disabled.
[Setting condition]
 The condition set by ADCMPLER.CMPLTSA is met when ADCMPCR.CMPAE = 1
[Clearing condition]
 0 is written after reading 1
CMPSTOCA Flag (Compare Window A Internal Reference Voltage Compare Flag)
This flag is a status flag that indicates the internal reference voltage comparison result. When the comparison condition
set by ADCMPLER.CMPLOCA is met at the end of A/D conversion, this flag is set to 1.
Writing 1 to the CMPSTOCA flag is disabled.
The value 1 cannot be written to the CMPSTOCA bit.
[Setting condition]
 The condition set in by ADCMPLER.CMPLOCA bit is met when ADCMPCR.CMPAE = 1
[Clearing condition]
 0 is written after reading 1
