Thank you Alain!
Yes the app note was very useful as it turned out the spec sheet for the MS5541 was translated from Chinese to English and some of the more necessary information was missing! The "AN510" filled in some of the blanks. It also turned out that this device is sensitive to timing and Intersema decided to use strange methodes of SPI communications such as sending 21 bits and not 24! I am very happy that there are people such as you as well as many others that are willing to assist and teach. Thank you all. Best, Ed
