DESCRIPTION
D7–D4
GPIO1_x Output Control
0000: GPIO1_x is disabled.
0001: GPIO1_x used for audio serial data bus ADC word clock
0010: GPIO1_x output = clock mux output divided by 1 (M = 1)
0011: GPIO1_x output = clock mux output divided by 2 (M = 2)
0100: GPIO1_x output = clock mux output divided by 4 (M = 4)
0101: GPIO1_x output = clock mux output divided by 8 (M = 8)
0110: GPIO1_x output = short-circuit interrupt
0111: GPIO1_x output = AGC noise interrupt
1000: GPIO1_x = general-purpose input
1001: GPIO1_x = general-purpose output
1010: GPIO1_x output = digital microphone modulator clock
1011: GPIO1_x = word clock for audio serial data bus (programmable as input or output)
1100: GPIO1_x output = hook-switch/button-press interrupt (interrupt polarity: active-high, typical interrupt
duration: button pressed time + clock resolution. Clock resolution depends on debounce programmability.
Typical interrupt delay from button: debounce duration + 0.5 ms)
1101: GPIO1_x output = jack/headset detection interrupt
1110: GPIO1_x output = jack/headset detection interrupt OR button-press interrupt
1111: GPIO1_x output = jack/headset detection OR button press OR short-circuit detection OR AGC
noise-detection interrupt
GPIO1_x Clock Mux Output Control
0: GPIO1_x clock mux output = PLL output
1: GPIO1_x clock mux output = clock divider mux output
GPIO1_x Interrupt Duration Control
0: GPIO1_x interrupt occurs as a single active-high pulse of typical 2-ms duration.
1: GPIO1_x interrupt occurs as continuous pulses until the interrupt flags register (register 96) is read by
the host.
GPIO1_x General-Purpose Input Value
0: A logic-low level is input to GPIO1_x.
1: A logic-high level is input to GPIO1_x.
GPIO1_x General-Purpose Output Value
0: GPIO1_x outputs a logic-low level.
1: GPIO1_x outputs a logic-high level.
