12.12.1 Set Address (Command: 0xD0, Data: write 1 byte)
The Set Address command is used to set the USB assigned address and enable the
(embedded) function. The address set in the device will take effect after the status stage
of the control transaction. After a bus reset, DEV_ADDR is set to 0x00, and DEV_EN is
set to 1. The device will respond to packets for function address 0x00, endpoint 0 (default
endpoint).
