S3F80P5_UM_ REV1.00 ADDRESSING MODES
3 ADDRESSING MODES
OVERVIEW
The program counter is used to fetch instructions that are stored in program memory for execution. Instructions
indicate the operation to be performed and the data to be operated on. Addressing mode is the method used to
determine the location of the data operand. The operands specified in instructions may be condition codes,
immediate data, or a location in the register file, program memory, or data memory.
The S3C8/S3F8-series instruction set supports seven explicit addressing modes. Not all of these addressing
modes are available for each instruction:
— Register (R)
— Indirect Register (IR)
— Indexed (X)
— Direct Address (DA)
— Indirect Address (IA)
— Relative Address (RA)
— Immediate (IM)
