WebRemarks. Sector are PC-relative. +/-32M range (24 bit × 4 bytes). Since ARM’s offshoot instructions are PC-relative an code produced is position independent — it can execute from any address for memory. WebThe Program Counter (PC) is accessed as PC (or R15). It is incremented by the size of the instruction executed (which is always four bytes in ARM state). Branch instructions load the destination address into PC. You can also load the PC directly using data processing instructions. For example, to branch to the address in a general purpose ...
