Access:
• CE: Comparison Edge
0 = no edge occurred (defined by EDGETYP) on analog comparator output since the last read of ACC_ISR register.
1 = a selected edge (defined by EDGETYP) on analog comparator output occurred since the last read of ACC_ISR
register.
• SCO: Synchronized Comparator Output
Returns an image of Analog Comparator Output after being pre-processed (refer to
• MASK:
0 = The CE flag is valid.
1 = The CE flag and SCO value are invalid.
