Chapter 51: LPC43xx/LPC43Sxx JTAG, Serial Wire Debug (SWD), and
51.6.2 Cortex debug connector (10-pin)
shows the Cortex debug connector (10-pin). This connector provides support
for Serial Wire and JTAG in a very small connector. The 10-pin Cortex debug connector
can access to all SWD, SWV, and JTAG signals.
51.6.3 Cortex Debug + ETM connector (20-pin)
If the debug trace feature will be used, there is also a debug-with-trace connector
specification as shown in
. This small 20-pin (0.05") connector provides access
to SWD, SWV, JTAG, and ETM (4-bit) signals.
