ENERGY MEASUREMENT INTERRUPTS

The Energy Measurement part of the ADE75XX/ADE71XX has

its own interrupt vector for the 8052 core – Vector address

0x004B – see Interrupt Vectors section. The bits set in the

Interrupt Enable Register 1 SFR (MIRQENL, 0xD9), Interrupt

Enable Register 2 SFR (MIRQENM, 0xDA), and Interrupt

Enable Register 3 SFR (MIRQENH, 0xDB) enables the energy

measurement interrupts that are allowed to interrupt the 8052

core. If an event is not enabled, it cannot create a system

interrupt.

The ADE interrupt stays active until the status bit that has

created the interrupt is cleared. A status bit of the ADE irq

status register (1, 2 or 3) is cleared when a zero is written the bit

to clear and acknowledge the event.
