SWD programming / debug interface on the STM32L073 - SWO??

The STM32 STM32L0x3 ref manual (RM073) and STM32L073 datasheet both show only 2 pins for the SWD programming interface:

- PA13 (SWDIO)

- PA14 (SWCLK)

But the schematic for the STM32L073 Nucelo PCB shows PB3 connected as SWO.

I dont see any reference to PB3 being part of the debug interface in the STM32L073 reference manual, datasheet or Cube MX configuration software.

Is PB3 part of the debug interface or not?

Please advise.

NOT supported on CM0(+) devices, board used for several parts.

The "Debug Communications Channel" can be implemented via an "Event Recorder" method

ST has a free license for Keil on CM0(+) devices

Hi Clive, So I only need to connect power, ground, PA13, PA14 & Reset for programming and debug? Thanks, Mark. Get Outlook for Android<>
