OUTPUT SWITCH
When the device is configured with a 2-wire interface the CSB/GPIO pin can be used as a switch
control input to automatically disable the speaker outputs and enable the mono output. For example
when a line is plugged into a jack socket. In this mode, enabled by setting GPIOSEL=001, pin
CSB/GPIO switches between mono and speaker outputs (e.g. when pin 12 is connected to a
mechanical switch in the headphone socket to detect plug-in). The GPIOPOL bit reverses the polarity
of the CSB/GPIO input pin.
Note that the speaker outputs and the mono output must be enabled for this function to work (see
Table 39). The CSB/GPIO pin has an internal de-bounce circuit when in this mode in order to prevent
the output enables from toggling multiple times due to input glitches.

THERMAL SHUTDOWN
The speaker outputs can drive very large currents. To protect the WM8510 from overheating a
thermal shutdown circuit is included. The thermal shutdown can be configured to produce an interrupt
when the device temperature reaches approximately 125
section for details.
