The Event Type Filter field determines which event types will be stored in the event log. This field
is a 8 bit mask. Every bit in this mask represents a event type. When a mask bit is set all events
with the subsequent event type will be stored in the event log. When a mask bit is cleared the
event data of the subsequent event type will be discarded.

the event data of the subsequent firmware module will be discarded. The table below describes
what bit belongs to which firmware module.
