3.3 Pin Descriptions
The following tables are a summary of the functional characteristics of MCU pins. Ta-
ble 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 indi-
cates that a pin can also be used for general-purpose input, output, or both. The I/O
port designation is given when it applies. Table 3-3 shows characteristics of power
pins. Refer to Figure 3-1 for port organization.
