_legacyfs_online_stmicro_images_0693W00000biv0xQAA.pngIn the datasheet of STM32WB5MMG, BOOT0 does not need to connect pull-up resistors and pull-down resistors, just connect GND or VCC directly.

In STM32WB5MM DK schematic,Do swdio and swclk need to be connected with pull-up or pull-down resistors? I want to connect swclk, swdio and swo directly as shown in the picture. Is this 22R resistor necessary?
