Sequential or Random mode. This mode cannot be changed by means of this page, it can only be changed by means of the OCP. Therefore the value set for this bit is ignored. Event Type Filter: 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. Event Type Cmd Response Event Trace Data Low Level Trace Customer Events Recovered Error Hard Error Mask Bit 01h 02h 04h 08h 10h 20h 40h 80h Event Module Filter: The Trace Module Filter field determines which firmware module stores events. This field contains a 16 bit mask. Every bit in this mask represents a firmware module. When a mask bit is set the subsequent module is allowed to store its event data in the event log. When a mask bit is cleared the event data of the subsequent firmware module will be discarded. The table below describes what bit belongs to which firmware module.

Filter:
The
Event

Filter
field
determines

will
be

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

log.
When
a

is
cleared
the

of
the

will
be
discarded.
