DAP
NINA-B50 series modules provide a Debug Access Port (DAP) to debug and trace the core system of
the module. On NINA-B50 series modules, the SWD interface is used as the external connection
interface of DAP.

SWO
NINA-B50 supports a 1-bit Serial Wire Output (SWO) trace port for efficiently accessing core trace
information from outside of the module. The SWO pin is used to stream-out trace information from
various parts of the module, including the Data Watchpoint and Trace (DWT) part, Instrumentation
Trace Macrocell (ITM) part, and Breakpoint Unit (BPU) part.
