Memory Map
The data stored in the GOT-F900 is classified into word data (D) and bit data (M).
An address is assigned to each data, and each data is positioned as described below.
14
Data Area
The m icrocom puter specifies data by "address". The screen creation softw are specifies data by "D " or "M ".
1) Word data (D)
There are 4096 word devices (D0 to D4095). A serial number (address) is assigned to each of them.
a) Word data (16 bits)
Each 8-bit word data is lined in the order of upper side (H) and lower side (L).
b) Double word data (32 bits)
Each 16-bit word data is lined from the higher address to the lower address.
When a 32-bit numeric value is displayed on the GOT-F900, if two word devices are located in the
reverse order, the correct value is not displayed because the most significant bit is regarded as
the sign (+ or -).
