The following Diagnostic Events are supported:
NOTE: Any Alarm or Diagnostic 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 key-
pad or by means of the digital communication interface). If 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.
