ABSTRACT:
When a loop connection associated with a port is detected while the port is in an Untested state ST3, a state machine corresponding to the port shifts from the state ST3to a Loop_disabled state ST4. The state machine then shifts from state ST4to a Sleep1 state ST5while maintaining a Loop_disabled value set at 1. When the state machine in state ST5detects a bus reset, the state machine shifts from state ST5to state ST4. Subsequently, the bus reset detection further shifts the state machine from state ST4to state ST3.
