Instruction Summary - Motorola MC68030 User Manual

lEI
Besides the operation code, which specifies the function to be performed,
an instruction defines the location of every operand for the function. Instruc-
tions 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 registers.
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 INTRODUC-
TION
contains register information.
Effective address information includes the registers, displacements, and ab-
solute addresses for the effective address mode. SECTION 2 DATA ORGANI-
ZATION AND ADDRESSING CAPABILITIES
describes the effective address
modes in detail.
Certain instructions operate on specific registers. These instructions imply
the required registers.
