description: |
Defines the configuration and output drive for the General Purpose
Input and Output pin (GPIO1). Its value is a pair, the first value is for
the configuration type and the second value is for the output drive
type. The array is defined as <GPIO1_CFG GPIO1_DRV>
configuration for the GPIO pin can be one of the following:
0 - disabled
1 - GPIO1 is configured as a general-purpose output (GPO)
2 - (default) GPIO1 is configured as a device interrupt output (IRQ)
3 - GPIO1 is configured as a secondary ASI output (SDOUT2)
4 - GPIO1 is configured as a PDM clock output (PDMCLK)
8 - GPIO1 is configured as an input to control when MICBIAS turns on or
off (MICBIAS_EN)
9 - GPIO1 is configured as a general-purpose input (GPI)
10 - GPIO1 is configured as a master clock input (MCLK)
11 - GPIO1 is configured as an ASI input for daisy-chain (SDIN)
12 - GPIO1 is configured as a PDM data input for channel 1 and channel 2
(PDMDIN1)
13 - GPIO1 is configured as a PDM data input for channel 3 and channel 4
(PDMDIN2)
14 - GPIO1 is configured as a PDM data input for channel 5 and channel 6
(PDMDIN3)
15 - GPIO1 is configured as a PDM data input for channel 7 and channel 8
(PDMDIN4)
output drive type for the GPIO pin can be one of the following:
0 - Hi-Z output
1 - Drive active low and active high
2 - (default) Drive active low and weak high
3 - Drive active low and Hi-Z
4 - Drive weak low and active high
5 - Drive Hi-Z and active high
