Signal Connections for In-System Programming and Debugging
A
Make connection J1 if a local target power supply is used, or make connection J2 if the target is powered from the
debug or programming adapter.
debug or programming adapter.
B
The device RST/NMI/SBWTDIO pin is used in 2-wire mode for bidirectional communication with the device during
JTAG access, and any capacitance that is attached to this signal may affect the ability to establish a connection with
the device. The upper limit for C1 is 2.2 nF when using current TI tools.
