Problem with timing LPSPI (i.MXRT1062)

I have a problem with LPSPI (i.MXRT1062). It's about starting the transmission (Master).

Starting PSC + CLOCK begins after ~ 2 us after writing data  to registry (LPSPI->TDR = data or TCR.TXMSK = 1). Is this normal behavior?

 

On the picture: TDR is updated with the falling edge of the yellow signal. Clock starts 2u later.
