		<!-- I2C control interface commands -->
		<h2 id="ykush3_i2c_commands">I2C interface commands</h2>
		<p>
			YKUSH3 boards have an I2C interface alowing them to be connected to a
			I2C bus and communicate to other devices in that bus.
			The board can be configured in I2C slave mode, for other I2C devices to be
			able to control the switching of the downstream ports, or in master mode
			to be able to control other I2C devices.
		</p>
		<p>
			To configure the board to operate I2C in slave mode and be controlable
			by a master I2C device the user must enable the 
			<i>i2C control interface</i> feature.
		</p>
		<p>
			When the board is configure with I2C in master mode it provides a
			USB to I2C gateway funcionality.
			With this USB to I2C gateway functionality a user can communicate with
			a slave I2C device, connected in the same I2C bus than YKUSH3 board,
			from the command line of the PC using <i>ykushcmd</i> application.
		</p>

		<h3>Command usage</h3>
		<p class="command_line">
			ykushcmd ykush3 [OPTION]... 
		</p>
		<p>The following options are available:</p>
		<table>
			<tr>
				<td>--i2c-enable-control</td>
				<td>
					Enables I2C as a control interface.
					This will configure I2C in slave mode.
				</td>
			</tr>
			<tr>
				<td>--i2c-disable-control</td>
				<td>
					Disables I2C as a control interface.
				</td>
			</tr>
			<tr>
				<td>--i2c-enable-gateway</td>
				<td>
					Enables USB to I2C gateway functionality.
					This will configure I2C in master mode.

				<td>
					Disables USB to I2C gateway functionality.
				</td>
			</tr>
			<tr>
				<td>--i2c-set-address &lt;address&gt;</td>
				<td>
					Set the board I2C address. 
					The <i>address</i> should be in hexadecimal representation
					with a <b>0x</b> prefix.
					Example: 0x1F for 7-bit address 0011111.
					This address is only used when the board is configured
					with I2C in slave mode.
