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.

Data Sheet

After power is supplied to the ADE7816 and communication

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.

WTHR1 = 0x000002

WTHR0 = 0x000000

VARTHR1 = 0x000002

VARTHR0 = 0x000000

PCF_A_COEFF = 0x400CA4 (50Hz)

PCF_B_COEFF = 0x400CA4 (50Hz)

PCF_C_COEFF = 0x400CA4 (50Hz)

PCF_D_COEFF = 0x400CA4 (50Hz)

PCF_E_COEFF = 0x400CA4 (50Hz)

PCF_F_COEFF = 0x400CA4 (50Hz)

DICOEFF = 0xFFF8000
