Description
This bit is set if any of the ADE status flags that are enabled to generate an ADE interrupt is set. This bit is
automatically cleared when all of the enabled ADE status flags are cleared.
Reserved.
Logic 1 indicates that the fault mode has changed according to the configuration of the ACCMODE register.
Logic 1 indicates that the reactive power sign has changed according to the configuration of the ACCMODE register.
Logic 1 indicates that the active power sign has changed according to the configuration of the ACCMODE register.
Logic 1 indicates that an interrupt has been caused by apparent power no load detection. This interrupt is also
used to reflect that the part is entering the I
Logic 1 indicates that an interrupt has been caused by reactive power no load detection.
Logic 1 indicates that an interrupt has been caused by active power no load detection.
Description
Logic 1 indicates that a pulse on CF2 has been issued. The flag is set even if the CF2 pulse output is not
enabled by clearing Bit 2 of the MODE1 register.
Logic 1 indicates that a pulse on CF1 has been issued. The flag is set even if the CF1 pulse output is not
enabled by clearing Bit 1 of the MODE1 register.
Logic 1 indicates that the VAHR register has overflowed.
Logic 1 indicates that the VARHR register has overflowed.
Logic 1 indicates that the WATTHR register has overflowed.
Logic 1 indicates that the VAHR register is half full.
Logic 1 indicates that the VARHR register is half full.
Logic 1 indicates that the WATTHR register is half full.
Description
Reserved.
Logic 1 indicates that new data is present in the waveform registers (Address 0xE2 to Address 0xE7).
Logic 1 indicates that the current channel has exceeded the IPKLVL value
Logic 1 indicates the end of the energy accumulation over an integer number of half-line cycles.
Logic 1 indicates that no zero crossing on the line voltage happened for the last ZXTOUT half-line cycles.
Logic 1 indicates detection of a zero crossing in the voltage channel.
