40.7.6 ACC Interrupt Status Register
Name: ACC_ISR
Address: 0x40040030
Access: Read-only
• 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 Figure 40-1 on page 967).
If INV = 0
SCO=0ifinn>inp
SCO=1ifinp>inn
If INV = 1
SCO=1ifinn>inp
SCO=0ifinp>inn
• MASK:
0 = The CE flag is valid.
1 = The CE flag and SCO value are invalid.
