To program/debug EFR32BG22C222F352GM32 do we need PTI DATA and PTI FRAME? Why the PTI DATA , PTI FRAME, TX , RX connections are given in the 10 pin programming connector?

If we use one 6 pin like VDD, VSS, RST, SWO, SWDIO, and SWCLK for programming/debugging purpose then wha will the problems we have to face, please guide me I am confused.

Can't we use separately these  PTI DATA , PTI FRAME, TX , RX connections?

  • PTI, UART RX and TX is not needed if you only need to program the EFR32.

    These signals are important for debugging/troubleshooting during development stage.
