10.5.1.7
The Address Register (UADDR) contains the unique
USB address that the USB will decode. The register is
reset to 00h after the RESET input has gone active or
the USB has decoded a USB Reset signaling. That will
initialize the address register to decode address 00h
as required by the USB specification. The USB
address must be written by the MCU during the USB
SETUP phase.
REGISTER 10-7: USB ADDRESS REGISTER (UADDR: 196h)
10.5.1.8
This register is used by the USB firmware libraries for
USB status.
REGISTER 10-8: RESERVED SOFTWARE LIBRARY REGISTER (USWSTAT: 197H):.
