ST7DALIF2

Instruction set

123/171

19.1.7

Relative mode (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 (direct)

The offset follows the opcode.

Relative (indirect)

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