BT branches to the target address if Boolean register bs is true.
The target instruction address of the branch is given by the address of the BT instruction, plus the sign-extended 8-bit imm8 field of the instruction plus four. If the Boolean register bs is false, execution continues with the next sequential instruction.
The inverse of BT is BF.
