Scanning the ADC
Figure 24-10
shows a block diagram of the ADC with all relevant control and observe signals. The Boundary-scan cell from
Figure 24-9
is attached to each of these signals. The ADC need not be used for pure connectivity testing, since all analog
inputs are shared with a digital port pin as well.
