The
PassControl
command allows Driver488 to give control to another controller on the bus. After
passing control, Driver488 enters the Peripheral mode. If Driver488 was the System Controller, then it
remains the System Controller, but it is no longer the Active Controller. The Controller now has
command of the bus until it passes control to another device or back to Driver488. The System
Controller can regain control of the bus at any time by issuing an
Abort
command.
