Description
Device Select*¹
When the host controller function is selected, these
bits specify the device address of the function
device.
These bits should be set after setting the address to
the DEVADDn register corresponding to the value to
be set in these bits. For example, before setting
DEVSEL to 0010, the address should be set to the
DEVADD2 register.
