Scanning the Analog
Comparator
240
ATmega169/V
The relevant Comparator signals regarding Boundary-scan are shown in Figure 113.
The Boundary-scan cell from Figure 114 is attached to each of these signals. The sig-
nals are described in Table 104.
The Comparator need not be used for pure connectivity testing, since all analog inputs
are shared with a digital port pin as well.
