RT1172 using a 3-wire spi mode to configure lvds panel

[shawn_123]

hello dear nxp engineer

    I am using a rt1172 MCU want to connect a lvds panel, this panel is from a small company, which is configure via 3-wire spi the image format is 18bit RGB. 

my first question is from the SDK example i found the lpspi example incude polling/b2b/interrupt  i am not so familiar with this mcu, how to configure the 3-wire spi, so i can write cmd and  data the configure the panel in the initialization process. i learned that 3-wire spi only using CS, SCLK,and a bi-directional IO wire. how to change the lpspi demo to code to achieve this target, or i need to rewrite it totally, please give some help or doc support, thanks a lot!
