Test Clock—TCK is a test clock input signal used to synchronize the
JTAG test logic. It has an internal pull-up resistor.
This input is 5 V tolerant.
Test Data Input—TDI is a test data serial input signal used for test
instructions and data. TDI is sampled on the rising edge of TCK and
has an internal pull-up resistor.
This input is 5 V tolerant.
Test Data Output—TDO is a test data serial output signal used for
test instructions and data. TDO is tri-statable and is actively driven in
the shift-IR and shift-DR controller states. TDO changes on the falling
edge of TCK.
Test Mode Select—TMS is an input signal used to sequence the test
controller’s state machine. TMS is sampled on the rising edge of TCK
and has an internal pull-up resistor.
This input is 5 V tolerant.

GPIO0-3- The General Purpose I/O pins are used for con-
trol and handshake functions between the DSP and exter-
nal circuitry. Each Port B GPIO pin may be individually
programmed as an input, output or disconnected
