Terminal Configuration and Functions

4.3

Signal Descriptions

The device contains many peripheral interfaces. In order to reduce package size and lower overall system

cost while maintaining maximum functionality, many of the terminals can multiplex up to eight signal

functions. Although there are many combinations of pin multiplexing that are possible, only a certain

number of sets, called IO Sets, are valid due to timing limitations. These valid IO Sets were carefully

chosen to provide many possible application scenarios for the user.

TI has developed a Windows-based application called Pin Mux Utility that helps a system designer select

the appropriate pin-multiplexing configuration for their device-based product design. The Pin Mux Utility

provides a way to select valid IO Sets of specific peripheral interfaces to ensure the pin-multiplexing

configuration selected for a design only uses valid IO Sets supported by the device.
