Description
Indicates that an interrupt was caused by the 0-to-1 transition of the MSB of the active energy register, i.e., the
AENERGY register is half full.
Indicates that an interrupt was caused by a SAG on the line voltage.
Indicates the end of energy accumulation over an integer number of half line cycles as defined by the content
of the LINECYC register—see the Line Cycle Energy Accumulation Mode section.
Indicates that new data is present in the waveform register.
This status bit reflects the status of the ZX logic ouput—see the Zero-Crossing Detection section.
Indicates that a temperature conversion result is available in the temperature register.
Indicates the end of a reset (for both software or hardware reset). The corresponding enable bit has no
function in the interrupt enable register, i.e., this status bit is set at the end of a reset, but it cannot be enabled
to cause an interrupt.
Indicates that the active energy register has overflowed.
Indicates that waveform sample from Channel 2 has exceeded the VPKLVL value.
Indicates that waveform sample from Channel 1 has exceeded the IPKLVL value.
Indicates that an interrupt was caused by the 0 to 1 transition of the MSB of the apparent energy register, i.e.,
the VAENERGY register is half full.
Indicates that the apparent energy register has overflowed.
Indicates that an interrupt was caused by a missing zero crossing on the line voltage for the specified number
of line cycles—see the Zero-Crossing Timeout section.
Indicates that the power has gone from negative to positive.
Indicates that the power has gone from positive to negative.
