1. Function (subroutine) implementation requires Control instructions. (T/F) 2. We have one register file in LC-3 and all the instructions in all subroutines read and write from that one register file. 3. We use regular load and store instructions to access the status and data registers of a Memory Mapped IO (MMIO) device. 4. We use a handshaking protocol to control the exchange of data between a microcontroller and an asynchronous I/O device. 5. In a system with an OS, a programmer can directly access I/O registers.
