Interrupt Status Register (10h) / Reset Interrupt Status Register (11h)
The Interrupt Status Register is used to determine the source of an interrupt event. When an interrupt event occurs in the
ADE7754, the corresponding flag in the Interrupt Status Register is set logic high. The
IRQ
pin will go active low if the
corresponding bit in the Interrupt Mask register is set logic high. When the MCU services the interrupt, it must first carry
out a read from the Interrupt Status Register to determine the source of the interrupt. All the interrupts in the Interrupt Status
Register stay at their logic high state after an event occurs. The state of the interrupt bit in the Interrupt Status register is reset
to its default value once the Reset Interrupt Status register is read.

0
Indicates that an interrupt was caused by the 0 to 1 transition of the MSB of the AENERGY
register (i.e. the AENERGY register is half-full)
Indicates that an interrupt was caused by a SAG on the line voltage of the Phase A
Indicates that an interrupt was caused by a SAG on the line voltage of the Phase B
Indicates that an interrupt was caused by a SAG on the line voltage of the Phase C
Indicates that an interrupt was caused by a missing zero crossing on the line voltage of the
Phase A
Indicates that an interrupt was caused by a missing zero crossing on the line voltage of the
Phase B
Indicates that an interrupt was caused by a missing zero crossing on the line voltage of the
Phase C
Indicates a detection of rising zero crossing in the voltage channel of the phase A
Indicates a detection of rising zero crossing in the voltage channel of the phase B
Indicates a detection of rising zero crossing in the voltage channel of the phase C
In Line energy accumulation, it indicates the end of an integration over an integer number
of half line cycles (LINCYC)

Indicates that the ADE7754 has been reset
Indicates that an interrupt was caused when the selected voltage input is above the value
in the PKVLV register.
Indicates that an interrupt was caused when the selected current input is above the value
in the PKILV register.
Indicates that new data is present in the Waveform Register.
Indicates that an interrupt was caused by the 0 to 1 transition of the MSB of the
VAENERGY register (i.e. the VAENERGY register is half-full)
