Note: The EVENT registers hold information about events that have occurred in MAX8939/MAX8939A/MAX8939B. Events are trig-
gered by a change in the status registers, which contains the status of the monitored signals. When an EVENT bit is set in the
event register the IRQ signal shall be asserted (unless the IRQ is to be masked by a bit in the IRQ mask register). The IRQ is also
masked during the power-up sequence and are not released until the event registers have been read for the first time. The event
registers are automatically cleared during read-out operation automatically. The event registers may be read-out in page mode.
New events that occur during read-out are delayed before they are passed to the event register, ensuring that the host controller
does not miss them.
