Hi Mario,
You can use SSI interface module, but I suggest you to select SPI frame format by configuring the SSI module because of following reasons (TI Synchronous Serial Interface as an example):
1. When the data frames are transmitted continuously, the SSI format's SSIFss signal is pulsed High for one SSICLK period while the last bit(LSB) on the SSITx/SSIRx data line is being transmitted(refer to Figure 1 as below). But for standard SPI timing, the SSIFss signal is pulsed to High after the last bit(LSB) on the SSITx/SSIRx data line is transmitted(refer to Figure 2). ADS8326 has the same timing requirement as standard SPI in Figure 3.
2. The SSI format drives the data on the rising edge of SSICLK and latches the data on the falling edge. But ADS8326's SPI timing is opposite and transmits the data on the falling edge of DCLOCK and the mater/system can capture the each bit on the rising edge DCLOCK clock.(Figure 1 vs Figure 3)
I hope this is helpful for you. Thanks.
