4.3 Signal Descriptions

The AM335x device contains many peripheral interfaces. In order to reduce package size and lower overall system cost while maintaining maximum functionality, many of the AM335x 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 I/O Sets, are valid due to timing limitations. These valid I/O Sets were carefully chosen to provide many possible application scenarios for the user.

Texas Instruments has developed a Windows-based application called Pin Mux Utility that helps a system designer select the appropriate pin-multiplexing configuration for their AM335x-based product design. The Pin Mux Utility provides a way to select valid I/O Sets of specific peripheral interfaces to ensure the pin-multiplexing configuration selected for a design only uses valid I/O Sets supported by the AM335x device.
