CONNECT A ‘1’ INDICATES THAT A DEVICE IS CONNECTED ON THIS PORT OF THE HUB
ENABLED A ‘1’ INDICATES THAT THIS PORT IS ENABLED
SUSPEND A ‘1’ INDICATES THAT THIS PORT IS SUSPENDED
OVERCURRENT A ‘1’ INDICATES THAT OVERCURRENT CONDITION EXISTS ON THIS PORT.
IN MODE 0 OF OPERATION, THIS BIT IS THE SAME FOR ALL PORTS.
IN MODE 1, INDIVIDUAL PORT OVERCURRENT INDICATION IS POSSIBLE.
RESET A ‘1’ INDICATES THAT BUS RESET ON THIS PORT IS IN PROGRESS.
WHEN RESET IS COMPLETED (NORMAL DURATION OF 10MS), THIS BIT INDICATES A ‘0’.
POWER A ‘1’ INDICATES THAT POWER IS SUPPLIED TO DOWNSTREAM PORTS.
SINCE THE PDIUSBH11 SUPPORTS GANG MODE POWER SWITCHING,
THIS BIT IS THE SAME FOR ALL PORTS.
LOW SPEED A ‘1’ INDICATES THAT LOW SPEED DEVICE IS CONNECTED TO THIS PORT.
THIS BIT IS ONLY VALID WHEN CONNECT BIT IS A ‘1’.
Port Status Change Byte
The description for the Port Status Change Byte is similar to the Port Status Byte except that the value of the bits are ‘1’ only when a change
has occurred.
