    SPI, devices requires SSI high during readout

    Hi

    The ADC device, MCP33131D-10 requires SDI be held high during the complete cycle. Below is a screen capture from the datasheet. See Note 1.

    How do I do that?

    Thank you

    Found it. Just set the transfer value to 0xFFFF for 16 bits, or 0xFF for byte transfers.
