UART MEMORY?????

Might a (few) more "?" make this post's (appearance) even more disagreeable?    How badly would a forum page (loitered) w/"?" look?

MCU manual - UART Section - "knows" and can detail...

Hi oscar,

First calm down. Multiple punctuation, to me at least, it's like screaming, rushing and that well can be quite rude and discourage help from other users.
Second this is real simple info to find in the datasheet.
It can seem pretty big and daunting but it's everything there after all and you might find that finding a specific info in the middle of all that is not that hard.

Take the info your looking for.
Well open your part datasheet - you failed to state which one, no mater, all the Tiva datasheets follow this - and in adobe reader or other PDF reader, you will see bookmarks! These bookmarks are divided by specific peripheral, you will see the UART peripheral in there. If you collapse the UART bookmark you will see more "sub"-bookmarks in there. There's beginning that summarizes the features of the peripheral (the info you are looking for is so basic that it's there), there's the block diagram, a functional description - that if you collapse that bookmark you will find it divided by various features, described with further detail (really useful!) -, then it follows some initialization examples with registers, the register map with a table of all the register of the peripherals and it ends with each register description.

To help you with your search of info, the Tiva team not only added those neat bookmarks and used the same structure of data through each peripheral, but also took advantage of the PDF features and if you see a page number or a title/topic, you can actually just click it and it will take you there! You can try that in the Index or in phrases that tell you "go to page something for more info".

I hope it helps

Hello Oscar,

UART FIFO is 16 locations deep. Data sheet mentions the same.
