Instruction set

137/188

12.1.7

Relative modes (Direct, Indirect)

This addressing mode is used to modify the PC register value by adding an 8-bit signed

offset to it.

The relative addressing mode consists of two submodes:

Relative mode (Direct)

The offset follows the opcode.

Relative mode (Indirect)

The offset is defined in memory, of which the address follows the opcode.
