Half-Duplex 2-wire spi?

[Helpful]

I'm working with a sensor that communicates over spi, but it uses a single wire for miso and miso. Is there any alternative to just bitbaning the protocol? Specific sensor (for reference) is the adns2620. Thanks!

I think you mean MSIO and MOSI not miso and miso.
