USB hub status registers. Procedure to set the device address:
1. After USB reset, the device responds to default address 0, and hub configuration = 0.
2. USB host controller issues SET_ADDRESS request to the device. (INTRB asserted)
3. Micro-controller recognizes the request, then set DEVADR register with appropriate value.
4. Micro-controller prepares the status stage of SET_ADDRESS request by programming
TXCTL0 register.
5. When the hub configuration value is not equal zero, HCONFIG is set to one.
USB reset will clear this register.
