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.
Instruction groups
The ST7 family devices use an Instruction Set consisting of 63 instructions. The instructions
may be subdivided into 13 main groups as illustrated in the following table:
