JTAG / SWD Multiplexer (Schematic page 23)

Buffers

A set of tri-state buffers is used to multiplex JTAG and SWD signals, and also multiplex the UART
VCP_TX signal with the SWO signal. LED D2 (DEBUG ACTIVE) is lit on when these buffers are
enabled. To avoid signal contention, external JTAG debuggers should not be connected when
DEBUG ACTIVE is on.
