- Serial Wire Debug technology (SWD), specifically the Serial Wire Debug Port (SW-DP) for the EFM32, is used as the interface between the on-chip debug module and the development environment on a computer. SW-DP is a 2-pin debug interface which offers a high performance and low pin count alternative to JTAG.

SW-DP is a 2-pin debug interface which offers a high performance and low pin count alternative to JTAG. SWD is often used as an acronym for both the SW-DP and SWJ-DP (Serial Wire JTAG Debug Port). The EFM32 does not implement SWJ-DP.

Jul 9, 2021 · Connecting to these pins allows an external device (such as a debug probe) to communicate directly with the Serial Wire Debug Port (SW-DP). The SW-DP can then access one or several Access Ports (APs) that give access to the rest of the system.
The 32-bit low-power microcontroller (MCU) family features short wake-up time from energy-saving modes and a wide selection of peripherals. Based on the powerful ARM® Cortex®-M3 core, the Gecko MCU family includes 25 devices that offer flash memory configurations up to 128 kB, 8–16 kB of RAM and CPU speeds up to 32 MHz.

Jul 9, 2021 · ETM data is only available after the trace GPIO pins have been configured as described above. Until the pins have been configured in firmware, there is no way to receive ETM data on the ETM bus outside of the MCU (i.e. using a debug probe such as i-Jet Trace).
Pin connections are given with a module prefix followed by a short pin name: CMU_CLKOUT1 (Clock management unit, clock output pin number 1) The location for the pin names given in the module documentation can be found in the device-specific datasheet.
Jul 9, 2021 · Answer. EFM32 MCUs use the ARM CoreSight on-chip debug and trace interface. Serial Wire Debug technology (SWD), specifically the Serial Wire Debug Port (SW-DP) for the EFM32, is used as the interface between the on-chip debug module and the development environment on a computer.
