Thanks for quick response. vs1053 manual 7.5.1. means "Bytes are always send msb first" - where can i change?

anyhow the question is, is it possible to change dataorder SSP to msbf?

Thank you, that is helpful. i missunderstood the figures in the vs1053 manual, but you are right, it is the same as in chapter 18/lpc manual
