Multiple nRF52 on single JTAG connection

[Gaurav]

Can I program multiple nRF52832 controllers simultaneously using a single JTAG connection? If yes, How may I can do? If No, Please explain.

I have worked with two solutions to do this:

One solution would be to use analog muxes to mux the SWDCLK and SWDIO signals.

A simpler solution is possible. You can run the SWDCLK signal through an AND port. Even though the AND port solution works, a faulty device could disrupt the SWDIO signal.
