Condition flags
Examples
R0, LookUpTable
R7, localdata
These instructions do not change the flags.
• bit[0] of the loaded value must be 1 for correct execution, and a branch occurs to this
• if the instruction is conditional, it must be the last instruction in the IT block.
halfword-aligned address
; Load R0 with a word of data from an address
; labelled as LookUpTable
; Load a byte value from an address labelled
; as localdata, sign extend it to a word
; value, and put it in R7
