I'm designing a board with the CYBLE-013025-00.

I need to use the SWD interface, for programming and debug (it's standard for the ARM architecture).

From datasheet (https://www.cypress.com/file/374396/download) I can see that pin n. 6 (padname P15) is SWDIO, but I cannot find the reference for SWCLK signal.

What is the pin for the SWCLK signal?

Hello,

CYBLE-013025 module uses HCI UART interface for programming.

You may use the HCI UART pins.

The Serial Wire Debug (SWD) debug/trace messages can also be output through the HCI UART port that’s onboard. The SWD pins are muxed with HCI UART and are used in such a manner that the hardware and firmware can auto-detect the presence of SWD or the HCI host

Please refer to the below links:
