110/167
Table 56.
Relative mode (Direct, Indirect)
This addressing mode is used to modify the PC register value, by adding an 8-bit signed
offset to it.
Table 57.
The relative addressing mode consists of two submodes:
Relative (Direct)
The offset is following the opcode.
Relative (Indirect)
The offset is defined in memory, which address follows the opcode.
Instruction groups
