					SpaceWire port will wait until the
					other end of the link tries to
					make a connection and will then
					automatically start.
13	Start	‘0’			When set then the SpaceWire				R/W
					link will initiate start-up as
					defined in the SpaceWire
					standard [AD1]: the SpaceWire
					port will try to make a connection
					with the other end of the link.
14	Disable	‘0’			When set then the SpaceWire				R/W
					link will be disabled as defined in
					the SpaceWire standard [AD1]:
					the SpaceWire port will not start
					and will not respond to any
					attempt to make a connection by
					the other end of the link.
15	Deactivate	‘0’			When set the DOUT and SOUT				R/W
					serial SpaceWire signals will be
					deactivated dependent on the
					state of the SpaceWire link
					interface. The DOUT and SOUT
					deactivate output state
					mappings are listed below:
					ErrorReset	Æ Deactivate
					ErrorWait	Æ Deactivate
					Ready	Æ Deactivate
					Started	Æ Enabled
					Connecting	Æ Enabled
					Run	Æ Enabled
					Note: DOUT is deactivated one
					system clock cycle before SOUT
					to ensure simultaneous edges
					due to output port deactivation
					do not occur.
