Table 19. METER_CONTROL Register (0x84) – Read/Write

BIT

NAME

OPERATION

DEFAULT

METER_RESET

Resets energy meter and tick counter until cleared; 1 = reset, 0 = reset cleared

METER_HALT

Halts energy meter and tick counter from accumulating; 1 = halted, 0 = not halted

TICK_OVERFLOW

Tick counter has overflowed; 1 = overflowed, 0 = not overflowed

METER_OVERFLOW

Energy meter accumulator has overflowed; 1 = overflowed, 0 = not overflowed

ALERT_GENERATED

Latched to 1 when an alert is generated and can only be cleared via I2C; 1 = alert generated,

0 = alert has not been generated

EE_LOCK

EEPROM lock status, read only; 1 = EEPROM is factory locked, 0 = EEPROM is not factory locked

1:0

Reserved

Read only, always returns 0
