7 Multiplexed Peripherals

With the large number of multiplexed digital I/O present on the AM263x and AM263Px MCU IOMUX, designers should make full use of the TI System Configuration tool (SYSCONFIG) to experiment and plan different pin multiplexing scenarios before committing the design to hardware. The resulting SYSCONFIG pin multiplexing configurations can then be used for schematic capture, layout, and software driver creation.
