CICBC Write Enable. If set, the CICBC may be written. If cleared, the
CICBC is read only.
Segment Quiesced (Owner). When in owner mode, if this bit is set, the bus
segment is Quiesced; the arbiter is locked and the bus is idle.
Handover Requested (Drone). When in drone mode, if this bit is set, the
bus owner has requested a handover. This bit is cleared when the handover
is complete. When this bit transitions from 0 to 1, the CICBS flag in the INT
register will be set.
Mode Change. If set, the bus segment interface has changed modes. When
this bit transitions from 0 to 1, the CICBS flag in the INT register will be set.
