escalate the interchange to a higher reset level.
This command is used to switch control from the currently active SPE to the
standby. This type of interchange is called a planned, soft, demand or requested
interchange. Interchanges caused by hardware faults or the SPE-Select
hardware switches are called spontaneous or hard interchanges. Planned
interchanges are discussed under:
