Instruction Set Summary
Besides the operation code, which specifies the function to be performed, an instruction
defines the location of every operand for the function. Instructions specify an operand
location in one of three ways:
1. Register Specification — A register field of the instruction contains the number of the
register.
2. Effective Address — An effective address field of the instruction contains address
mode information.
3. Implicit Reference — The definition of an instruction implies the use of specific regis-
ters.
The register field within an instruction specifies the register to be used. Other fields within
the instruction specify whether the register selected is an address or data register and how
the register is to be used. Section 1 Introduction contains register information.
Effective address information includes the registers, displacements, and absolute
addresses for the effective address mode. Section 2 Data Organization and Addressing
Capabilities describes the effective address modes in detail.
Certain instructions operate on specific registers. These instructions imply the required
registers.
