2 Signal Descriptions
2.1 MC68HC16V1 Pin Characteristics
Table 2 shows MCU pins and their characteristics. All inputs detect CMOS logic levels. All inputs can
be put in a high-impedance state, but the method of doing this differs depending upon pin function. Re-
fer to Table 4 for a description of output drivers. An entry in the discrete I/O column of the MCU pin
characteristics table indicates that a pin has an alternate I/O function. The port designation is given
when it applies. Refer to Figure 1 for information about port organization.
