NOTE: Any Alarm Events that may have occurred (Event 0 to Event D) are
stored in the internal status register. All detected events (if corresponding
bit in the latch register is not masked) remain stored until the register is
manually reset (by means of the digital communication interface). If the event
corresponding bit in the latch register is masked (disabled), the event will be
indicated as long as it is active (no latching). The status Alarm Event Register
is mapped to the SRAM (volatile memory). In case of power interruption, the
status Event Register will be automatically reset.
