2 Signal Descriptions
2.1 Pin Characteristics
MC68331TS/D
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 Table 4 , for a description of output drivers. An entry in the discrete I/O column of Ta-
ble 2 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.
