Hi, While reading the code in cfspi_tx(): while ((dspi->sr & 0x0000F000) >= 4) ;

I don't see the point of checking "(dspi->sr & 0x0000F000) >= 4)".

I'm wondering if it should be while ((dspi->sr & 0x0000F000) >> 12) >= 4) ; or simply while (dspi->sr & 0x0000F000) ;

Current code actually has the same effect as "while (dspi->sr & 0x0000F000) ;".

comments?
