TMS570LC4357: BSR baud rate register

Part Number: TMS570LC4357

I have code that I use to punch a "P" and "M" value into the SCI BSR registers.

In halgogen, I have SCI3 and SCI2 (LIN2) enabled...not using LIN...using SCI2 as standard uart

I run the code and pass the P and M into the function I have, and point to sciREG2....I see the register load correctly

I run the code and pass the P and M into the function I have, and point to sciREG3....I ONLY SEE THE lower end of the register update!...not the bits 27-24 (M) get loaded..??????

see attached?

what am I missing?...I'm sure it is something stupid simple

as always appreciate your help!!!!!!!sci2sci3.docx
