10.13 ADRL pseudo-instruction
Load a PC-relative or register-relative address into a register.
If the assembler cannot construct the address in two instructions, it generates an error message and the assembly fails. You can use the

Architectures and range
The available range depends on the instruction set in use:
The given range is relative to a point four bytes (in Thumb code) or two words (in ARM code) after the address of the current instruction.
When assembling Thumb instructions,
