The following tables summarize functional characteristics of MCU pins. Table 3-1
shows types of output drivers. Table 3-2 shows all inputs and outputs. Digital inputs
and outputs use CMOS logic levels. An entry in the Discrete I/O column indicates that
a pin can also be used for general-purpose input, output, or both. The I/O port desig-
nation is given when it applies. Table 3-3 shows characteristics of power pins. Refer
to Figure 3-1 for port organization.
