• Manufacturer Part Number: ade7953
• Description: Single Phase, Multifunction Metering Ic With Neutral Current Measurement Ade7953
• Manufacturer: Analog Devices, Inc.

The Current Channel B apparent energy no-load interrupt
can be enabled by setting the VA_NOLOADB bit (Bit 8) in the
IRQBENB register (Address 0x22F and Address 0x32F). When
this bit is set, an apparent energy no-load event on Current
Channel B triggers the IRQ alternative output (see the
Channel B Interrupts
section).

Apparent Energy No-Load Status Bits
In addition to the apparent energy no-load interrupt, the ADE7953
includes two unlatched status bits that continually monitor the
no-load status of Current Channel A and Current Channel B.
The VANLOAD_A and VANLOAD_B bits are located in the
ACCMODE register (Address 0x201 and Address 0x301). These
bits differ from the interrupt status bits in that they are unlatched
and can, therefore, be used to drive an LED.
