Data Sheet
MEMORY OVERVIEW
The ADE5166/ADE5169/ADE5566/ADE5569 contain three
memory blocks, as follows:
? 62 kB of on-chip Flash/EE program and data memory
? 256 bytes of general-purpose RAM
? 2 kB of extended internal RAM (XRAM)
The 256 bytes of general-purpose RAM share the upper 128 bytes
of its address space with the SFRs. All of the memory spaces are
shown in Figure 81. The addressing mode specifies which
ADE5166/ADE5169/ADE5566/ADE5569
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,
Address 0x20 to Address 0x2F, can be accessed through Bit
Address 0x00 to Bit Address 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
Address 0x20 through General-Purpose RAM Address 0x2F
can be seen in Figure 85.

Bit addressing can be used for instructions that involve Boolean
variable manipulation and program branching (see the Instruction
Set section).
Special Function Registers (SFRs)
Figure 83. Lower 128 Bytes of Internal Data Memory
Address 0x80 through Address 0xFF of general-purpose RAM
are shared with the SFRs. The mode of addressing determines
which memory space is accessed, as shown in Figure 84.
0×FF
Special function registers are registers that affect the function
of the 8052 core or its peripherals. These registers are located
in RAM at Address 0x80 through Address 0xFF. They are
accessible only through direct addressing, as shown in Figure 84.
