There are potentially two separate issues here.

One is learning the instruction set, the other is learning the particular 
vendors assembler.

For the instruction set the ARM Architecture reference Manual is a pretty 
straightforward explanation of the instruction set.

For the assembler I'm afraid there is not much choice other than the 
particular vendors documentation.  A lot of assembler manuals are rather 
sparse (although good ones do exist for some products), the worst are down 
right cryptic and in some cases close to non-existent.

If there are particular small cases that are giving you trouble you might 
see if anyone here can clarify them.  There are people here who use all of 
the popular ARM tools.
