Explanation on Addressing
Direct addressing
The addressing, which is indicated by dir in the instructions list, is used for accessing the area from 0000H
to 00FFH. In this addressing, the higher one byte of the address is 00H. Specify the lower one byte with the
operand.
Figure B.1-1 shows an example.
Figure B.1-1 Example of Direct Addressing
Extended Addressing
The addressing, which is indicated by ext in the instructions list, is used for accessing the entire area of 64
KB. In this addressing, specify the higher one byte of the address with the first operand and the lower one
byte with the second operand.
Figure B.1-2 shows an example.
