where:

ADR determines the address by adding an immediate value to the PC, and writes the result to
the destination register.
ADR produces position-independent code, because the address is PC-relative.
If you use ADR to generate a target address for a BX or BLX instruction, you must ensure that
bit[0] of the address you generate is set to1 for correct execution.
