The Comparator need not be used for pure connectivity testing, since all analog inputs are
shared with a digital port pin as well.

From Digital Logic
1. Do not enable more than one clock source as main clock at a time.
2. Scanning an Oscillator output gives unpredictable results as there is a frequency drift between
3. The clock configuration is programmed by fuses. As a fuse is not changed run-time, the clock
summaries the scan registers for the external clock pin XTAL1, oscillators with
the Internal Oscillator and the JTAG TCK clock. If possible, scanning an external clock is
preferred.
configuration is considered fixed for a given application. The user is advised to scan the 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 disconnect-
ing 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 can not make a XTAL Oscillator requiring inter-
nal capacitors to run unless the fuse is correctly programmed.
