• Return from suspend condition by USB reset (by INT_CLKON interrupt)
When UDC stops CLK in suspend condition, UDC can not detect USB reset and
control CLK in suspend condition as above mentioned.
In case CLK is stopped in suspend condition, UDC can detect USB reset and return
from suspend condition by supplying CLK (USBCR1<USBCLKE>=1) after detecting
INT_CLKON interrupt.
