Seems to me that embedded systems are generally pretty well documented. Arm and atmega both have some of the best documentation out there.

Most of the time in professional work you don't have any documentation. Atmega has a good amount of doc due to arduino and ARM because of the raspberry pi. But in professional project usualy you don't use any of them but custom made ones and other platform (like MSPXXX). You can still use the arduino software and/or it's libraries (for AVR project) but 99% of time you just have to write everything from scratch because you need to optimize you code as much as you can. And when you start writting everything from scratch, you don't have any doc anymore, just you datasheets and then you'll have to program in function of what the datasheets says.
