@ -57,6 +57,9 @@ Configuration variables:
- **id** (**Required**, :ref:`config-id`): The id to use for this MCP23008 component.
- **address** (*Optional*, int): The I²C address of the driver.
Defaults to ``0x20``.
- **open_drain_interrupt** (*Optional*, bool): Configure the interrupt pin to open-drain mode.
Useful when the MCP23008's power supply is greater than 3.3 volts. Note that this pin
will require a pull-up resistor (to 3.3 volts) when this mode is enabled.
