Hi TI-Team

There is some error in the documentation of TivaWare and the implementation.

The software returns only 0 or 1.

Docu:

Returns:

Code:

//!
//! \return Returns the number of elements read from the SSI receive FIFO.

//*****************************************************************************
int32_t
SSIDataGetNonBlocking(uint32_t ui32Base, uint32_t *pui32Data)
{
    //
    // Check the arguments.
    //
    ASSERT(_SSIBaseValid(ui32Base));

    //
    // Check for data to read.
    //
    if(HWREG(ui32Base + SSI_O_SR) & SSI_SR_RNE)
    {
        *pui32Data = HWREG(ui32Base + SSI_O_DR);
        return(1);
    }
    else
    {
        return(0);
    }
}
