FORMAT 16: CONDITIONAL BRANCH
OPERATION
The instructions in this group all perform a conditional Branch depending on the state of the CPSR condition
codes. The branch offset must take account of the prefetch operation, which causes the PC to be 1 word (4
bytes) ahead of the current instruction.
The THUMB assembler syntax is shown in the following table.
