The book is good, but it isn't cheap. But hey, lack of knowledge on these details is even more expensive!
We also found some example code for a test board from Motorola (we're actually using a Motorola CPU with ARM core), and it turns out that they also have an "Interrupt Controler" application note that's quite helpful (unlike the CPU reference manual, I might add..)
Yes, I was going to mention something related to that. With the "advanced/vectored interrupt controllers" that are all the rage now, there are some nifty tricks you can use to really boost interrupt handling performance. I have examples, but if there are some in your manuals then go with them.
