ARM Register Documentation

Other Parts Discussed in Thread: OMAP-L138, AM1808, AM1810

Can someone point me to the documentation for the ARM registers? I am specifically looking for the meaning of the CPSR.M bits. I searched the OMAP-L138 data sheet, the ARM Compiler User Guide, the ARM Assembler User Guide, and the ARM Tech Reference Manual. This information really must be sensitive....:)

Thx,

Hmmm...nothing on the OMAP-L138 webpage. Odd oversight. Never noticed that. The ARM core is a standard ARM926EJ-S core with ARM9 memory architecture. Probably could get docs from ARM themselves or the other guys, Atmel. Staying within TI, the closest is the AM series.

AM1808/AM1810 ARM Microprocessor System Reference Guide(Rev. A)

Hopefully, some TI guys will suggest a more official reference. I think the CPSR is called PSR in the above doc.
