Scanning the Analog Comparator
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.

same clock option as to be used in the final system. The enable signals are supported in the
scan chain because the system logic can disable clock options in sleep modes, thereby dis-
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.
