DAC7760 (Eval-Board) interfacing with TMS320F28377D (EVAL-BOARD),trying to communicate with SPI.

Hello, 

I have attached below the waveform capture of the SPI bus.

I am  able to LATCH (rising edge of the Latch signal) exactly/AFTER LSB of the Data.  ButNOT GETTING any OUTPUT / register value back when i tried reading it .

Tried using TX-FIFO interrupts, to get an interrupt after I send 24 bits of data so that I rise the LATCH, but the interrupt is not working fine.

Could anyone  please suggest ,where I am going wrong. 

In the figure-

Waveform 1 - SCLK

Waveform2 - MOSI Line

Waveform 3 - Latch (rising edge)

Thank You, 

Prashanth
