Preliminary Technical Data
ADE7169F16
Both direct and indirect addressing can be used to access
General Purpose RAM from 0x00 through 0x7F but indirect
addressing must be used to access General Purpose RAM with
addresses in the range from 0x80 through 0xFF because they
share the same address space with the Special Function
Registers (SFRs).
Rev. PrD | Page 75 of 140
The 8052 core also has the means to access individual bits of
certain addresses in the General Purpose RAM and Special
Function Memory spaces. The individual bits of General
Purpose RAM addresses 0x20 through 0x2F can be accessed
through their bit addresses 0x00 through 0x7F. The benefit of
bit addressing is that the individual bits can be accessed quickly,
without the need for bit masking, which takes more code
memory and execution time. The bit addresses for General
Purpose RAM addresses 0x20 through 0x2F can be seen in
Figure 58.

Figure 58: Bit Addressable Area of General Purpose RAM
Bit addressing can be used for instructions that involve Boolean
variable manipulation and program branching—see the
Instruction set.
Special Function Registers:
Special Function Registers are
registers that affect the function of the 8051 core or its
peripherals. These registers are located in RAM with addresses
0x80 through 0xFF. They are only accessible through direct
addressing as shown in Figure 57 .
The individual bits of some of the SFRs can be accessed for use
in Boolean and program branching instructions. These SFRs are
labeled as bit-addressable and the bit addresses are given in the
SFR Mapping.
Extended Internal RAM (XRAM):
The ADE7169F16 provides
256 bytes of extended on-chip RAM. No external RAM is
supported. This RAM is located in addresses 0x0000 through
0x00FF in the Extended RAM space. To select the Extended
RAM memory space, the extended indirect addressing modes
are used. The internal XRAM is enabled in the Configuration
SFR (CFG, 0xAF) by writing 01 to CFG[1:0].

Code Memory:
Code and data memory are stored in the
16kbyte Flash memory space. No external code memory is
supported. To access Code memory, Code Indirect addressing is
used.
ADDRESSING MODES
The 8052 core provides several addressing modes. The
addressing mode determines how the core will interpret the
memory location or data value specified in assembly language
code. There are six addressing modes as shown in Table 59:
