Port Feature Selector Table
The Hub Controller will respond with a STALL if Port0 or a
port higher than Port4 is addressed in this request.
Get_Bus_State
When a Get_Bus_State is detected, the Hub Controller will
sample the bus status of Ports 1, 2, 3 and 4, at each EOF2
and will store the value in a register known as the
Port_Bus_State registers. The value of the D- signal (pin
DM[1:4]) will be in bit 0 and the value of the D+ signal
(DP[1:4]) will be in bit 1of each port’s Port_Bus_State regis-
ter. All other bits will be 0. The values of these two register
bits will be transferred to the Host upon receipt of the
Get_Bus_State request, if the setup packet from Host is
decoded as:
The Hub Controller will respond with a STALL if Port0 or a
port higher than Port4 is addressed in this request.
Data Response 000000 [D+] [D-].
Get_Hub_Descriptor
Get_Hub_Descriptor returns the Hub Descriptor. The last
word of the Get_Hub_Descriptor request specifies the
number of bytes AT43310 is to return. If the requested
number of bytes is less than the 9-bytes length of the Hub
Descriptor, AT43310 will return only the requested number
of bytes from the top of the descriptor. If the requested
number of bytes is more than 9, then the returned data will
be padded with trailing bytes of zeroes.
This action will be taken if the Setup packet from the Host is
decoded as:
