Get_Descriptor
Get_Descriptor returns the requested descriptor. The last
word of the Get_Descriptor request specifies the number of
bytes the AT43310 is to return. If the requested descriptor
is longer than the requested number of bytes, AT43310 will
return only the requested number of bytes from the top of
the descriptor. If the requested descriptor is shorter than
the requested number of bytes, then the AT43310 indicates
the end of the control transfer by sending a short data
packet.
The requested number of bytes from the top of AT43310’s
Device Descriptor will be returned, if the Setup packet from
host is decoded as:
The requested number of bytes from AT43310’s Configura-
tion Descriptor, Interface Descriptor, and Endpoint Descrip-
tor will be returned, if the Setup packet from the Host is
decoded as:
Get_Interface
The AT43310 has a single interface with a value of 0. If it
receives a Get_Interface Request with the value of 0000H
as wIndex (bytes 2 and 3), the AT43310 will return a single
byte with a value of 00H. For any other value of wIndex the
AT43310 will return a STALL.
Get Device Status
If the Setup packet from host is decoded as:
The Hub will return two bytes of data, byte 0 and byte 1, in
little endian order:
Byte 0, Bit 0 = 1, identifying the AT43310 as a self pow-
ered device.
Byte 0, Bit 1 = copy of bit 1 of the Controller_Status
Register. This bit reflects whether the AT43310’s
remote wakeup capability is enabled or disabled.
All other bits are set to 0.
