11. See the following sections to set up other metrology features:

a. Total Active Power

b. Total Apparent Power

c. Line Period Calculation:

1. It is recommended to configure CONFIG0:PERI-

OD_AVG_CFG[4:3] to 0x2 to average the period over

16 samples. This reduces the period jitter.

d. RMS of One Cycle:

1. It is recommended to configure CON-

FIG0:RMSONE_SRC_SEL[11] to 0x1 to use data from

before the HPF for the fastest response time.

2. It is recommended to configure CONFIG0:PERI-

OD_AVG_CFG[4:3] to 0x2 to average the period over

16 samples. This reduces the period jitter.

e. RMS of Half Cycle:

1. It is recommended to configure CON-

FIG0:RMSHALF_SRC_SEL[11] to 0x1 to use data from

before the HPF for the fastest response time.

2. It is recommended to configure CONFIG0:PERI-

OD_AVG_CFG[4:3] to 0x2 to average the period over

16 samples. This reduces the period jitter.

f. Peak Detection

g. Dip and Swells

h. Phase-Sequence Error Detection

i. Zero-Crossing Timeout

j. Neutral Current Mismatch

k. PEN Fault Detection

l. Waveform Streaming

12. Enable energy accumulation by setting the EGY_PWR_EN bit

in the EP_CFG register to 1.

13. It is recommended to enable CRC check of the configuration

registers. For more details, see the CRC of Configuration Reg-

isters section.

14. To prevent any changes to the ADE9178 configuration, enable

write protection by writing 1 to the CONFIG_LOCK register. For

more details, see the Configuration Lock section.

15. After the RUN bit of ADC_CONTROL (set in Step 10 Part d) is

set, the output registers update at a frequency shown in Table

26. For more details, see the Output Register Update Rates

section.

For more detailed information on how to set up the ADE9178 in an

EVSE application, refer to the application note, Using ADE9178 for

EV Charger Metrology Solution.
