LPC55S6 3-wire SPI

Hi all.

I use LPC55S6 MCU and I would like to interface this to the programmable gain amplifier PGA113 from TI.

The PGA113 have a 3-wire SPI interface to communicate from/to the master.

How can I connect the MCU to the the PGA113 on SPI interface? LPC55S6 MCU have a 4-wire SPI interface (CS, SCK, MISO, MOSI) and PGA have a 3-wire SPI interface (CS, SCK, SDIO).

Is there a NXP HW guide to do that?

Can you help me?

Thank you.

Gabriele.
