LDM – Load Multiple Registers
Architecture revision:
Architecture revision1 and higher.
Description
Loads the consecutive words pointed to by Rp into the registers specified in the instruction. The
PC can be loaded, resulting in a jump to the loaded target address. If PC is loaded, the return
value in R12 is tested and the flags are updated. The return value may optionally be set to -1, 0
or 1.
Operation:
I.
