3.2.2 Program Counter during Execution of the Branch Instruction (BR)
There are two ways to specify branching using the branch instruction. One is to specify the branch address in
the operand using the direct branch instruction (BR addr). The other is to branch to the address specified by the
address register using the indirect branch instruction (BR @AR).
The address specified by a direct branch instruction is placed in the program counter.
