(2) 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 or disabled based on the condition of the TRST signal. See the
Systems Control and Interrupts chapter of the
TMS320x2806x Piccolo Technical Reference Manual
(
SPRUH18
).
(3) Depending on your USB application, additional pins may be required to maintain compliance with the USB 2.0 Specification. For more
information, see the Universal Serial Bus (USB) Controller chapter of the
TMS320x2806x Piccolo Technical Reference Manual
(
SPRUH18
).
