Description
Indicates the end of a reset (for both software and hardware reset).
Reserved.
Logic 1 indicates that new data is present in the waveform registers (Address 0xE2 to Address 0xE7).
Logic 1 indicates that current channel has exceeded the IPKLVL value
Logic 1 indicates that voltage channel has exceeded the VPKLVL 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.
Description
Reserved.
When this bit is set, the FAULTSIGN bit set creates a pending ADE interrupt to the 8052 core.
When this bit is set, the VARSIGN flag set creates a pending ADE interrupt to the 8052 core.
When this bit is set, the APSIGN flag set creates a pending ADE interrupt to the 8052 core.
When this bit is set, the VANOLOAD flag set creates a pending ADE interrupt to the 8052 core.
When this bit is set, the RNOLOAD flag set creates a pending ADE interrupt to the 8052 core.
When this bit is set, the APNOLOAD flag set creates a pending ADE interrupt to the 8052 core.
Description
