2.2 DEVICE RESET OPERATION
A Device Reset operation is performed in the following conditions:
At device power-up.
When the Reset bit in the Device Control register is set to 1 (see
Section 2.8
"Device Control").
The Device Reset operation performs the following:
Aborts any device operation in progress and restarts device operation.
Sets all device registers to their "Reset" (default) value.
2.3 DEVICE NUMBER (Addr: 000 000; 00h)
This register is used to specify a unique address for each device on the bus.
