1. Direct addressing and index addressing

Each software component of our software has a unique address, which consists of a base address and an offset address. For example, D100 indicates that the base address is data register D and the offset address is 100.

You can follow an offset soft component (V/Z) after the offset address and add an offset value to this offset address. For example, D100V0 indicates that the base address is data register D, and the offset address is 100+V0.

Attention

The range of the V/Z offset register is [-32768, 32767], which can be offset forward.
