ADE7566/ADE7569/ADE7166/ADE7169
8052 MCU CORE ARCHITECTURE
The ADE7566/ADE7569/ADE7166/ADE7169 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 its
enhancements used in the ADE7566/ADE7569/ADE7166/
ADE7169.
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. A block diagram showing the
programming model of the ADE7566/ADE7569/ADE7166/
ADE7169 via the SFR area is shown in Figure 80.
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 power
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.
