Support for probe interface level translation #1069

Could you tell me if there is currently any support for probe interface voltage level translation, for example a possibility for outputting direction control signals for each bidirectional SWD line on the probe MCU GPIO? I am assuming level translation implementation using dedicated ICs with enable and direction control inputs for each data line.
Any suggestions would be very appreciated.

Thank you,
Mihails

Yes, this should be possible. Look at the lpc55xx implementation as an example as the MCU-Link uses bidirectional level translators in the way you describe.

https://github.com/ARMmbed/DAPLink/blob/dbb10a262c2cbcc0db879f0af12219445067ed79/source/hic_hal/nxp/lpc55xx/DAP_config.h#L326C1-L344C2

Implementing these functions can allow you to send the appropriate signals to the level shifter direction pins.
