[USB Address Register] USBA
The USB address register maintains the USB function control unit
address assigned by the host computer. When receiving the
SET_ADDRESS, keep it in this register. The values of this register
are
0
when the device is not yet configured. The values of this
register are also set to
0
when the USB block is disabled (bit 7 of
USB control register is set to
0
). In addition, no matter what
value is written to this register, it will have no effect on the set
value.
[USB Power Management Register] USBPM
The USB power management register is used for power manage-
ment in the USB FCU. This register needs to be set only when
using the remote wake-up to resume the MCU from suspend
mode.

USBA
Programmable function address (FUNAD0 to 6))
This register maintains the 7-bit USB function control unit address
assigned by the host CPU.
