In response to the standard USB request SET_ADDRESS, the firmware must write
the (enabled) device address to the Address register, followed by sending an empty
packet to the host. The
new
device address is activated when the device receives
acknowledgment from the host.
9.2.2
Mode register (address: 0Ch)
This register consists of 2 bytes (bit allocation: see
Table 20
).
The Mode register controls resume, suspend and wake-up behavior, interrupt activity,
soft reset, clock signals and SoftConnect operation.
