User’s Manual
Extended Addressing
Extended Addressing provides for two bytes (16 bits) of address to be
included in the instruction. This data can be an address to which a
program can jump or it can be an address where an operand is located.
Extended addressing is required for a program to jump from any location
in memory to any other location, or load and store data in any memory
location.
During extended addressing use, specify the source or destination address
of an operand. This notation (
memory at
The two bytes of address
The use of the parentheses always means that the value enclosed within
them is used as a pointer to a memory location. For example, (3200)
refers to the contents of memory at location 1200.
Indexed Addressing
In this type of addressing, the byte of data following the Op Code
contains a displacement that is added to one of the two index registers (the
Op Code specifies which index register is used) to form a pointer to
memory. The contents of the index register are not altered by this
operation.
An example of an indexed instruction is to load the contents of the
memory location (Index Register + Displacement) into the accumulator.
