Scanning the Analog
Comparator
2490Q–AVR–06/10
The relevant Comparator signals regarding Boundary-scan are shown in
Boundary-scan cell from
described in
The Comparator needs not be used for pure connectivity testing, since all analog inputs are
shared with a digital port pin as well.

connecting the Oscillator pins from the scan path if not provided. The INTCAP Fuses are not
supported in the scan-chain, so the boundary scan chain cannot make a XTAL Oscillator
requiring internal capacitors to run unless the fuse is correctly programmed.
