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 dis-
crete 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.
