LDR uses an address called a "Register Offset" address. Why? Group of answer choices The data value loaded is at an address in the memory. The data value loaded is the results of adding a register and immediate to obtain the reference for the data value Memory is accessed at a location that is a numeric value, starting at (offset from) 0 The ALU can only use register (not memory) values All data access is relative to a memory address or 0. The LDR command uses what units in the CPU? Select all that apply.
