2 Signal Descriptions

2.1 Pin Characteristics

The following table 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. Refer to the table MCU Driver Types 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 the MCU Block Diagram for information about port

organization.
