Table 100. Instructions supporting direct, indexed, indirect, and indirect indexed
Relative (direct, indirect)
This addressing mode is used to modify the PC register value, by adding an 8-bit signed
offset to it.
Table 101. Available relative direct/indirect instructions
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.
