How to connect HTS221TR via 3-wire SPI to uC? Is there any schematics or application note?

HTS221TR connecting via 3-wire SPI.

Is there any official app. note for this interface.

I suppose it is via connection MOSI and MISO through 10K resistor and then feeding it to a sensor.

But I would like to get some official input from STM because I need it for a customer.

Kind regards,

Danko

It depends on the microcontroller. If the microcontroller also support 3-wire SPI than only MOSI line is needed.
