Segment Reset. If set, this bus segment is being held in reset by the PCI
interface device or the CIC.
CICAC Write Enable. If set, the CICAC may be written. If cleared, the CICAC
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 CICAS 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 CICAS flag in the INT register will be set.
Owner. If set, this bus segment interface is in owner mode
RH. If set, this bus segment interface is in a Redundant Host slot
