Part 2 Signal/Connection Descriptions
2.1 Introduction
The input and output signals of the 56F8322 and 56F8122 devices are organized into functional groups,
as detailed in Table 2-1 and as illustrated in Figure 2-1 and Figure 2-2. In Table 2-2, each table row
describes the signal or signals present on a pin.
Note: See Table 1-1 for 56F8122 functional differences.
