IMX6 SPI 3-Wire

Hi all,

Currently I am having an IMX6 board connected with LCD controller via SPI as shown below




Here SDO and SDI on Slave side are connected together via a resistor to the slave. Hence the SPI interface is 3- Wire.


I read some posts saying that for SPI 3-Wire to work, we need to connect MOSI to MISO via resistor, which is not the case above.


Can some one please tell me whether the above design will work for SPI 3-Wire ?.


Thanks in advance.
