NOTE
- Except register Tn and Cn , data type of register is Byte and its order is opposite to usual controller , for example :
- + IW3 is a word which combined from IB3 and IB4 > High Byte of IW3 is IB3 ; Low Byte of IW3 is 1B4.
- + ID3 is Double Word which combined from IB3, I1B4, IB5 and IB6, and its order from highest to lowest is IB3, B4, IB5 andIB6. And please be attentive to use these registers, because their Data type is different with Data Length, it will need more than one register for each access, for example:
- ~ AIW6 which Data Type is Byte and Data Length is 1 Word, when it used for one word Numeric Entry , it will occupy two addresses AlB6 and AIB7 –
- ~ MD12 which Data Type is Byte and Data Length is Double Word > when it used for one word Numeric Entry, it will occupy four addresses MB12,MB13,MB14 and MB15; But data only stored in MB14 and MB15.
- IW3 which Data Type is Byte and Data Length is 1 Word , when it used for double word Numeric Entry, it will occupy for addresses IB3,1B4,IB5 and IB6 > order from highest to lowest byte is IB5,1B6,IB3 and 1B4.
