Aug 4, 2005 - The Instruction Set Architecture (ISA) of the LC-3 is defined as follows: Memory address space All other LC-3 instructions leave the condition codes unchanged. At this time, the LC-3 ISA specifies two exception conditions: privilege mode. Indicates the address of the next instruction to be executed. NB---When the LC-3 Simulator starts up, the PC is automagically set to address x0200. This is the MCR defined as having one bit to enable/disable the system clock. This is not The Instruction Set Architecture (ISA) of the LC-3b is defined as follows: Memory mapped I/O Input and Output are handled by load/store instructions using At this time, an LC-3b computer system provides only one I/O device that can LC-3 Instructions.

All instructions that write values into registers set the three condition code registers (i.e., the single-bit registers N 4. LC-3 Overview: Instruction Set. Opcodes. 15 opcodes.
