10 / 244 page  5 Device Comparison Table 5-1 shows a comparison between devices, highlighting the differences. Note Availability of features listed in this table are a function of shared IO pins, where IO signals associated with many of the features are multiplexed to a limited number of pins. The SysConfig tool should be used to assign signal functions to pins. This will provide a better understanding of limitations associated with pin multiplexing. Note To understand what device features are currently supported by TI Software Development Kits (SDKs), see the AM64x Software Build Sheet. Table 5-1.
