if LK then LR
If AA = 0, then the branch target address is the sum of LI || 0b00
sign-extended and the address of this instruction. If AA = 1, then
the branch target address is the value LI || 0b00 sign-extended.
If LK = 1, then the effective address of the instruction following
the branch instruction is placed into the link register.
Other registers altered:
Affected: Link Register (LR) (if LK = 1)
