Notes
USB time out happens when the USB cable is connected (VBUS level > 0.8V) and
USB RESET happens within a 400ms time out.
<USBHS_ENUM_TOUT> and <USBHS_LINK_TOUT> are automatically reset to
their default values, 0, in the following conditions:
Cold boot or hardware reset.
Download program received the reset command from the host to reboot the
module.
Successfully booted in the module firmware, which means time out values
are reset when time out happens in a previous boot.
Basically, the conditions above are terminate conditions that time out values are
effective only once.
