       Defines the configuration and output driver for the general purpose

       output pins (GPO).  These values are pairs, the first value is for the

       configuration type and the second value is for the output drive type.

       The array is defined as <GPO_CFG GPO_DRV>



       GPO output configuration can be one of the following:



       0 - (default) disabled

       1 - GPOX is configured as a general-purpose output (GPO)

       2 - GPOX is configured as a device interrupt output (IRQ)

       3 - GPOX is configured as a secondary ASI output (SDOUT2)

       4 - GPOX is configured as a PDM clock output (PDMCLK)



       GPO output drive configuration for the GPO pins can be one of the following:



       0d - (default) Hi-Z output

       1d - Drive active low and active high

       2d - Drive active low and weak high

       3d - Drive active low and Hi-Z

       4d - Drive weak low and active high

       5d - Drive Hi-Z and active high
