48 / 73 page  6.3.5 GPIO Supported Functionality The controller provides 52 general-purpose I/O that are available to support a variety of functions for many different product configurations. In general, most of these I/O pins support only one specific function based on a specific product configuration, although that function may be different for a different product configuration. A portion of the unused I/O can also be made available for TI test and debug use. Each of the following GPIO tables provides product-specific details on the allocated use of each of the GPIO for a specific supported product configuration. Table 6-14.
