“ RES ” in the register map means reserved bit(s).
Interrupt Vector Register is a READ ONLY register. Each bit in this register will be cleared when there are no
pending interrupts reported in the corresponding interrupt status registers.
This register displays all the Power Alarm and the Loop Closure interrupt of the device. A pending interrupt is
represented by a HIGH “1” in the respective bit. Writing 1 to that respective bit clears the pending interrupt.
