ADE5166/ADE5169/ADE5566/ADE5569
8052 MCU CORE ARCHITECTURE
Data Sheet
The ADE5166/ADE5169/ADE5566/ADE5569 have an 8052 MCU
core and use the 8051 instruction set. Some of the standard 8052
peripherals, such as the UART, have been enhanced. This section
describes the standard 8052 core and enhancements that have
been made to it in the ADE5166/ADE5169/ADE5566/ADE5569.

The special function register (SFR) space is mapped into the upper
128 bytes of internal data memory space and is accessed by direct
addressing only. It provides an interface between the CPU and all
on-chip peripherals. See Figure 81 for a block diagram showing
the programming model of the ADE5166/ADE5169/ADE5566/
ADE5569 via the SFR area.

All registers except the program counter (PC), instruction register
(IR), and the four general-purpose register banks reside in the
SFR area. The SFRs include control, configuration, and data
registers that provide an interface between the CPU and all on-
chip peripherals.
MCU REGISTERS
The registers used by the MCU are summarized in Table 57.
