SWD Interface sharing between nRF52 and MCU

[KPK]

We have an nRF52832 and an MSP430 on a custom board. We would like to program both the devices using SWD interface.

Would it be possible that both these devices can share the same SWDCLK pin? ( and using a jumper to switch the SWDIO while flashing)

Has anybody tried this? Any possible alternative approaches?

It would be recommended to switch both pins as the clk pin could leave the other device in unpredictable error state.

I agree that putting a jumper on both pins is the safest approach.
