Scanning the Analog
Comparator
2513C–AVR–09/02
The relevant Comparator signals regarding Boundary-scan are shown in Figure 91. The
Boundary-scan cell from Figure 92 is attached to each of these signals. The signals are
described in Table 87.
The Comparator need not be used for pure connectivity testing, since all analog inputs
are shared with a digital port pin as well.
