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 80.
The relative addressing mode consists of two submodes:
Relative (direct)
The offset follows the opcode.
Relative (indirect)
The offset is defined in the memory, the address of which 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:
