(1) The GPIO function (shown in bold italics) is the default at reset. The peripheral signals that are listed under them are alternate functions.
For JTAG pins that have the GPIO functionality multiplexed, the input path to the GPIO block is always valid. The output path from the
GPIO block and the path to the JTAG block from a pin is enabled/disabled based on the condition of the TRST signal. See the
TMS320x2803x Piccolo System Control and Interrupts Reference Guide (literature number SPRUGL8) for details.
