I/O Power Change Interrupt Register
This register generates an interrupt when an interface power domain is powered up or down. Note that a power domain that
is already up when the device resets (including wakeup from standby) also causes an interrupt in this register (which is not
seen by the CPU until the corresponding mask bit is set).
