Bcond is the only conditional instruction that is not required to be inside an IT block. However, it
has a longer branch range when it is inside an IT block.
These instructions do not change the flags.
• do not use PC in the BLX instruction
• for BX and BLX, bit[0] of Rm must be 1 for correct execution but a branch occurs to the target
• when any of these instructions is inside an IT block, it must be the last instruction of the IT
address created by changing bit[0] to 0
block.
