resistor is connected to host in OFF condition, this condition is equivalent condition
with USB_RESET signal by pull-down resistor on the host side. Therefore UDC is not
detected in USB_RESET until “0” is written to USBREADY register
This register informs finishing writing data to descriptor RAM on UDC.
After assigned data to descriptor RAM, write “0” to bit0.
