*1: Same as the other ports if this is being used for the output state. "Input enabled" means that the input function is
currently enabled; Pull-up/Pull-down or an input from the external is required.
*2: Outputs the initial output preceding this mode. Alternatively, this means "Input disabled" if the signal is input. "Input
disabled" means that the contents of a pin are not accepted internally, because the internal circuit is not in operation
although operation of the input gate nearest to the pin is currently enabled.
*3: In the input shutoff state, the input is masked ant the "L" level is passed to the internal.
*4: When operation stops due to a cause in the USB, the signal is input via the USB port. When it stops due to another cause,
the preceding state remains unchanged.
Note:
The mode transits to the standby mode is also inhibited during the USB is transferred.
