PRODUCTION DATA.
All the GPIO pins on thePCM186x software-controlled devices can be configured for various functions. They can each have their polarity inverted to make control of following circuits easier. See the control registers for each GPIO for a better explanation of mapping. (such as GPIO1_FUNC at Page.0 0x10)
The type of function can also be controlled, including such behavior as regular inputs, inputs with toggle detection, or sticky bits. The device can also be configured as an open drain output, so that multiple interrupt outputs from different devices in the system can be connected together.
