QUICK START
This section outlines the procedure for powering up and initializing
the ADE7816. Figure 23 shows a flow diagram of the initialization
steps. For detailed information, refer to the section of the data
sheet that pertains to each step, as indicated in Figure 23.

After power is supplied to the
is established, a set of registers must be written (see Figure 23).
Table 8 lists details about each register.
The registers listed in Table 8 are essential for correct operation.
After these registers are set, enable any meter-specific features
before enabling the DSP to begin the energy calculations.
NOTE THAT THE FINAL
REGISTER SHOULD BE
WRITTEN 3 TIMES TO
