ACCESSING THE ADE7754 ON-CHIP REGISTERS
All ADE7754 functionality is accessed via the on-chip registers. Each register is accessed by first writing to the
communications register and then transferring the register data. For a full description of the serial interface protocol, see
Serial
Interface
section of this data sheet.
Communications Register
The Communications register is an eight bit, write-only register which controls the serial data transfer between the ADE7754
and the host processor. All data transfer operations must begin with a write to the communications register. The data written
to the communications register determines whether the next operation is a read or a write and which register is being accessed.
Table VII below outlines the bit designations for the Communications register.

Description
0 to 5
A0 to A5
The six LSBs of the Communications register specify the register for the data transfer
operation. Table VIII lists the address of each ADE7754 on-chip register.
This bit is unused and should be set to zero.
When this bit is a logic one the data transfer operation immediately following the write to the
Communications register will be interpreted as a write to the ADE7754. When this bit is a logic
zero the data transfer operation immediately following the write to the Communications
register will be interpreted as a read operation.
