Immediate Addressing
In immediate addressing, the expression entered after the
number sign (#) is evaluated by the assembler and stored in the
memory address specified. This number is referred to as a literal
In extended direct addressing mode, the DPTR register points
to the address of the byte of extended RAM. The following code
moves the contents of extended RAM Address 0x100 to the
accumulator:
because it refers only to a value and not to a memory location.
Instructions using this addressing mode are slower than those

between two registers because the literal must be stored and
fetched from memory. The expression can be entered as a
symbolic variable or as an arithmetic expression; the value is
computed by the assembler.
Direct Addressing
With direct addressing, the value at the source address is moved
to the destination address. Direct addressing provides the fastest
execution time of all the addressing modes when an instruction
is performed between registers. Note that indirect or direct
addressing modes can be used to access general-purpose RAM
Address 0x00 through Address 0x7F. An instruction with direct
These two instructions require a total of seven clock cycles and
four bytes of storage in the program memory.
Extended Indirect Addressing
The internal extended RAM is accessed through a pointer to the
address in indirect addressing mode. The ADE7116/ADE7156/
ADE7166/ADE7169/ADE7566/ADE7569 have 256 bytes of
internal extended RAM, accessed through MOVX instructions.
External memory is not supported on the devices.
In extended indirect addressing mode, a register holds the address
of the byte of extended RAM. The following code moves the
contents of extended RAM Address 0x80 to the accumulator:
addressing that uses an address between 0x80 and 0xFF refers to
a special function memory location.
MOV
MOVX
R0,#80h
A,@R0
Indirect Addressing
With indirect addressing, the value pointed to by the register is
moved to the destination address. For example, to move the
contents of internal RAM Address 0x82 to the accumulator, use
the following two instructions, which require a total of four
clock cycles and three bytes of storage in the program memory:
These two instructions require six clock cycles and three bytes
of storage.
Note that there are 256 bytes of extended RAM, so both extended
direct and extended indirect addressing can cover the whole
address range. There is a storage and speed advantage to using
extended indirect addressing because the additional byte of

addressing available through the DPTR register that is not
needed is not stored.
Indirect addressing allows addresses to be computed and is
useful for indexing into data arrays stored in RAM.
Note that an instruction that refers to Address 0x00 through
Address 0x7F is referring to internal RAM, and indirect or
direct addressing mode can be used. An instruction with
indirect addressing that uses an address between 0x80 and 0xFF
refers to internal RAM, not to an SFR.
Extended Direct Addressing
The DPTR register (see Table 61) is used to access internal
extended RAM in extended indirect addressing mode. The
ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569
From the three examples demonstrating the access of internal
RAM from 0x80 through 0xFF and extended internal RAM
from 0x00 through 0xFF, it can be seen that it is most efficient
to use the entire internal RAM accessible through indirect
access before moving to extended RAM.
Code Indirect Addressing
The internal code memory can be accessed indirectly. This can
be useful for implementing lookup tables and other arrays of
constants that are stored in flash memory. For example, to move
the data stored in flash memory at Address 0x8002 into the
accumulator, use the following code:
have 256 bytes of XRAM, accessed through MOVX instructions.
External memory spaces are not supported on this device.

The accumulator can be used as a variable index into the array
of flash memory located at DPTR.
