Figure 9. EK-RA4M3 Debug Interface
5.2.2 Debug In
One 20-pin Cortex
®
Debug Connector at J20 supports JTAG, SWD and ETM (TRACE) debug. One 10-pin
Cortex
®
Debug Connector at J13 supports JTAG and SWD. Either of these connectors may be used for
external debug of the target RA MCU.
To configure the EK-RA4M3 board to use the Debug in mode, configure the jumpers using the following
table.
