20 GENERAL PURPOSE INPUTS / OUTPUTS (GPIO)
20.1 GENERAL DESCRIPTION
w
The WM8351 has thirteen general-purpose input/output (GPIO) pins; GPIO0 - GPIO12. These can be
configured as inputs or outputs, active high or active low, with optional on-chip pull-up or pull-down
resistors. Alternate functions are also available for each GPIO pin.
Note that different GPIO pins are supported on different power domains. The applicable power
domain is specific to a pin, not to a particular GPIO function. The power domains are as follows:
