CMPSTCHA1n Flag (n = 00 to 04, 11) (Compare Window A Flag)
This flag is comparison result status flag of channel (AN016 to AN020, AN027) to which window A comparison
conditions are applied. When the comparison condition set by ADCMPLR1.CMPLCHA1n is met at the end of A/D
conversion, each of these flags is set to 1. The
CMPSTCHA100
bit corresponds to AN016, the
CMPSTCHA104
bit
corresponds to AN020, and the
CMPSTCHA111
bit corresponds to AN027.
Writing 1 to the CMPSTCHA1n flag (n = 00 to 04, 11) is disabled.
