Instruction bytes giving faulty results

0x4240

Steps to get the wrong result

With cstool:

cstool -dr thumbbe 4240

 0  42 40  rsbs r0, r0, #0
        ID: 352 (rsb)
        op_count: 3
                operands[0].type: REG = r0
                operands[0].access: WRITE
                operands[1].type: IMM = 0x0
                operands[1].access: READ
                operands[2].type: REG = r0
                operands[2].access: READ
        Update-flags: True
        Registers read: r0
        Registers modified: cpsr r0
        Groups: IsThumb

You can see the order of the operands[1] and [2] is reversed.
