The J-Link On-Board (JLOB) debug interface supporting JTAG, SWD debug interface and also supports the
VCOM (Virtual COM port) function. The debug MCU is a Renesas RA4M2, programmed with J-Link firmware
licensed by Segger. This interface includes one USB micro-B connector (J6) for host debug through the J-
Link MCU, one 10-pin and one 20-pin debug header (supporting JTAG and SWD).
