The WM8978 has three dual purpose input/output pins.
The GPIO2 and GPIO3 functions are provided for use as jack detection inputs.
The GPIO1 function is provided for use as a jack detection input or a general purpose output.
The default configuration for the CSB/GPIO1 pin is to be an input.
When setup as an input, the CSB/GPIO1 pin can either be used as CSB or for jack detection,
depending on how the MODE pin is set.
Table 49 illustrates the functionality of the GPIO1 pin when used as a general purpose output.
