GPIO Output Data [7:0] (8 bits, MSB first).
These bits are sent to the pins GPIO [7:0] if their respective configuration bits (CFGPIO [7]
thru CFGPIO[0]) are set to the OUTPUT state. Refer to the GPIO configuration register
(index Reg # 18) for more information.

Codec Pins GPIO[7:0] Status (8 bits, MSB first).
These bits are areflection of the digitalvalues on pins GPIO[7:0]. If the GPIO Pinis configured
as an OUTPUT, the current setting of that OUTPUT bit will be returned in these statusbits.
If the GPIO is set to be an INPUT, the digital value on theGPIO input Pinwill be read. Refer to
the GPIO configuration register (index register 18) for more information.
