14.9.1 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 phase
of the setup token. (Alternately, issuing the Set Address command twice will set the
address in the device). At power on reset, the DEV_EN is set to 0. After bus reset, the
address is reset to 0x00. The enable bit is set to 1. The device will respond on packets for
function address 0x00, endpoint 0 (default endpoint).

14.9.2 Configure Device (Command: 0xD8, Data: write 1 byte)

A value of 1 written to the register indicates that the device is configured and all the
enabled non-control endpoints will respond. Control endpoints are always enabled and
respond even if the device is not configured, in the default state.
