11.3 Addressing Modes
The central processor unit (CPU) uses eight addressing modes for
flexibility in accessing data. The addressing modes provide eight
different ways for the CPU to find the data required to execute an
instruction. The eight addressing modes are:
Inherent
Immediate
Direct
Extended
Indexed, no offset
Indexed, 8-bit offset
Indexed, 16-bit offset
Relative
11.3.1 Inherent
Inherent instructions are those that have no operand, such as return
from interrupt (RTI) and stop (STOP). Some of the inherent instructions
act on data in the CPU registers, such as set carry flag (SEC) and
increment accumulator (INCA). Inherent instructions require no operand
address and are one byte long.
11.3.2 Immediate
Immediate instructions are those that contain a value to be used in an
operation with the value in the accumulator or index register. Immediate
instructions require no operand address and are two bytes long. The
opcode is the first byte, and the immediate data value is the second byte.
