SPI waveforms using niHSDIO as slave to DUT

Hi,

Is it possible to configure the pxi-6556 as a slave device and acquire SPI waveforms of data transfers coming from a Microcontroller configured as the master? The idea is to be able to characterize the SPI AC timing capabilities on the DUT (Microcontroller). I've researched examples and information in which the niHSDIO card is the master but what I really want is for the niHSDIO to emulate a slave device, and to be able to observe the SPI waveforms.

Thanks in advanced,

Scott
