When this bit is “1”, remote wakeup can be used. Remote wakeup is not disabled by
this bit. Therefore, if this bit shows disabled, remote wakeup must not be set. If it fills

UDC remote wakeup function can be used when it is permitted.
Setting remote wakeup by bus can be confirmed by bit7 of Current_Config register.
