Addressing

The assembly language uses different addressing modes and addressing considerations.

The addressing articles discuss addressing modes and addressing considerations, including:

Absolute addressing
An absolute address is represented by the contents of a register.
Absolute immediate addressing
An absolute immediate address is designated by immediate data.
Relative immediate addressing
Relative immediate addresses are specified as immediate date within the object code and are calculated relative to the current instruction location.
Explicit-based addressing
Explicit-based addresses are specified as a base register number, RA, and a displacement, D
Implicit-based addressing
An implicit-based address is specified as an operand for an instruction by omitting the RA operand and writing the .using pseudo-op at some point before the instruction.
Location counter
The assembler language program has a location counter used to assign storage addresses to your program’s statements.
