3.4 Pin Descriptions

The following tables are a summary of the functional characteristics of M68HC16 Z-

series MCU pins. Table 3-1 shows all inputs and outputs. Digital inputs and outputs

use CMOS logic levels. An entry in the âDiscrete I/Oâ column indicates that a pin can

also be used for general-purpose input, output, or both. The I/O port designation is giv-

en when it applies. Refer to Figure 3-1 for port organization. Table 3-2 shows types

of output drivers. Table 3-3 shows characteristics of power pins.
