ADE7566/ADE7569
ENERGY MEASUREMENT INTERRUPTS
The energy measurement part of the ADE7566/ADE7569 has
its own interrupt vector for the 8052 core, Vector Address 0x004B
(see the Interrupt Vectors section). The bits set in the Interrupt
Enable 1 SFR (MIRQENL, 0xD9), Interrupt Enable 2 SFR
(MIRQENM, 0xDA), and Interrupt Enable 3 SFR (MIRQENH,
Rev. 0 | Page 64 of 136
0xDB) enable 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. The status bit is cleared when a zero is
written to this register bit.
