ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569
8052 MCU CORE ARCHITECTURE
The ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/
ADE7569 have an 8052 MCU core and use the 8052 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
ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569.
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 of the
programming model for the ADE7116/ADE7156/ADE7166/
ADE7169/ADE7566/ADE7569 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 SFR registers 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 this section.
