SCI Enable Register
The SCI Enable Register (SCIEN) defines the type of events that can
generate an SCI. Refer to
SMB (Bit 0)
❏
Set to a logic 1 to allow generation of an SCI when SMB Alert is
active. SMB ALERT is active when logic 0.
❏
Write a logic 0 to this bit to disable an SCI for this event.
TEMP (Bit 1)
❏
Set to a logic 1 to allow generation of an SCI when TEMP is active.
❏
Write a logic 0 to this bit to disable an SCI for this event.
ALARM_A (Bit 3) and ALARM_B (Bit 2)
❏
Set to a logic 1 to allow the generation of an SCI when the
ALARM_A or ALARM_B go active.
❏
Write a logic 0 to these bits to disable an SCI for this event.
ENUM (Bit 4)
❏
Set to a logic 1 to allow generation of an SCI when the ENUM event
occurs.
❏
Write a logic 0 to this bit to disable an SCI for this event.
ENABLE (Bit 7)
❏
Set to a logic 1 to allow generation of an SCI by one of the events
above.
❏
Write a logic 0 to prevent the events from generating an SCI.
