Cortex Debug Connector (10-pin)
The CPU_45A-V3 board supports Serial Wire debug operation and Serial Wire viewer operation (via the SWO
signal when Serial Wire debug mode is used) through the 10-pin Cortex Debug Connector.
When using an external debugger connected to the 10-pin Cortex Debug Connector, the on-board debugger is
switched off.
