This explanation document introduces below example.

If you link the register address you have been using (= external register number) with Hitachi Register

address (=internal register address), the cases will be roughly divided into three cases and they are further

subdivided. But don't worry. Each case will be meticulously examined. The example begins very basic to a

bit complicated one.

[1] Hitachi register number list is not included in external register number (No overlapping) (ex1 to ex3)

A case where you use an external register number (16bit) and internal register number (16-bit) with the

1:1magnification(=no magnification),

A case where you multiply an external register by n (ex. Multiply 2) written to an internal register.

A case where data range includes minus value.

(Suppose the multiplication of external register and internal register is the same, for simple

explanation)

[2] Hitachi register address list include external register numbers. (Overlapping occurs, ex4 – ex6)

A case where the register address number (16-bit) you are going to use and the internal register

number you need to use overlaps. Let's assume the no multiplication is involved for simple explanation.

A case occurs that where the external register number overlaps with the high order of Hitachi register

number (32-bit).

A case occurs that where the external register number overlaps with the low order of Hitachi register

number (32-bit)
