Hi Vinayak,

The information on the SPI interface can be found in section 11.16.2 SPI Environment of the 66AK2Gx Multicore DSP + ARM Keystone II System-on-Chip (SOC) TRM (Rev. I). As described in that chapter, the SPI supports a 3 pin mode (SPI_CLK, SPI_SIMO & SPI_SOMI) or a 4 pin mode with adds an SPI_CS signal. The data uses a separate data input pin and data output pin and does not support a single data input/output pin.

Regards, Bill
