ENERGY MEASUREMENT INTERRUPTS
The energy measurement part of the ADE5166/ADE5169 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, Address 0xD9), Interrupt Enable 2
SFR (MIRQENM, Address 0xDA), and Interrupt Enable 3 SFR
Rev. 0 | Page 67 of 148
(MIRQENH, Address 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 0 is written
to this register bit.
