0000
GPIO1 Output Control
0000: GPIO1 is disabled
0001: GPIO1 used for audio serial data bus ADC word clock
0010: GPIO1 output = clock mux output divided by 1 (M=1)
0011: GPIO1 output = clock mux output divided by 2 (M=2)
0100: GPIO1 output = clock mux output divided by 4 (M=4)
0101: GPIO1 output = clock mux output divided by 8 (M=8)
0110: GPIO1 output = short circuit interrupt
0111: GPIO1 output = AGC noise interrupt
1000: GPIO1 = general purpose input
1001: GPIO1 = general purpose output
1010: GPIO1 output = digital microphone modulator clock
1011: GPIO1 = word clock for audio serial data bus (programmable as input or output)
1100: GPIO1 output = hook-switch/button press interrupt (interrupt polarity: active high, typical interrupt
duration: button pressed time + clock resolution. Clock resolution depends upon debounce
programmability. Typical interrupt delay from button: debounce duration + 0.5ms)
1101: GPIO1 output = jack/headset detection interrupt
1110: GPIO1 output = jack/headset detection interrupt OR button press interrupt
1111: GPIO1 output = jack/headset detection OR button press OR Short Circuit detection OR AGC
Noise detection interrupt

0
GPIO1 Clock Mux Output Control
0: GPIO1 clock mux output = PLL output
1: GPIO1 clock mux output = clock divider mux output
