What is the T_SW_DIR pin on STLINK-V3?

I can't find any information about what the T_SW_DIR pin is on the STLINK-V3 products. I am planning to use a STLINK-V3MODS programmer in a project, but I can't find any other information about this pin, other than it is an output. Does anyone know w...

I am now using 1.8V for VDD and 3.3V for VDDA. There is no USB. So I am fine having this power regime. The question I now have is on the programming aspects of the MCU (STM32G4A1KEU6). I have (we use) an STLINK programmer:STLINK-V3MINIE. All these time I

Designing with STM32L496

Hello Team,We are planning to use the MCU STM32L496QGI6 for one of our new projects.The MCU will be powered from a 1.8V source (since all external peripherals are working in 1.8V only).One of the SPI slaves is working in 3.3V, so we are planning to u...
