Get Interface Status
If the Setup packet from host is decoded as:
The Hub will respond with two bytes of data with all 0 value.
Get Endpoint Status
Get Endpoint Status returns two-bytes of data indicating
the stall status of the endpoint. The first bit of the first byte
returned reflects the status of the endpoint stall status bits
of the Controller_Status Register described in section 3.6.
These bits are set or cleared depending whether the end-
point is stalled or not:
Get Endpoint Status will execute if the following setup
packet is decoded as:
Set_Address
Set_Address sets the Hub’s address. The AT43310 will
save the value of bytes 2 and 3 into a temporary buffer.
After successful completion of the status stage, the
AT43310 transfers the temporary value into the
Hub_Address Register. The Hub_Address will be used as
the Hub’s address in all future transactions. Set_Address
will occur if the Setup packet from the Host is decoded as:
Set_Configuration
Set_Configuration sets bit 0 of the Controller_Status Regis-
ter according to the value of byte 2 of the Setup packet.
The AT43310 has only one configuration. The AT43310 will
only set the bit if byte 2 is either 00H or 01H, and bytes 3 to
7 are all zeroes. For all other values, the Hub will respond
with a STALL handshake packet. Set_Configuration occurs
if the Setup packet from host is decoded as:
