I am working on a question from a practice computer organization exam. The answer key to one of the questions says that both
LEA instructions of the LC-3 processor can access memory at an arbitrary distance (say #1000) from the instruction.
How is this correct?
I think that
LD uses PC relative mode, meaning it has 9 bits for offset or can access a memory location 256 spots away from the address in the program counter register(address of next instruction). That's not far enough for the criterion in the question. The argument for
LEA is the same.
Can anyone explain why I get a different answer to the key?
