DETECT
Headset Detection
0 => Disable headset detection
1 => Enable headset detection
Type of Headset Detected.
00 => No headset detected.
01 => Stereo headset detected.
10 => Cellular headset detected
11 => Stereo+cellular headset detected
Note: These two bits are valid only if the headset detection is enabled.
Headset Detection Flag.
0 => Headset is not detected
1 => Headset is detected.
Button Press Detection Flag.
0 => Button press is not detected
1 => Button press is detected.
Debouncing Programmability for Glitch Rejection During Headset Detection.
00 => 16 ms duration (with 2 ms clock resolution)
01 => 32 ms duration (with 4 ms clock resolution)
10 => 64 ms duration (with 8 ms clock resolution)
11 => 128 ms duration (with 16 ms clock resolution)

Enable GPIO2 for Headset Detection Interrupt

Enable GPIO1 for Headset Detection Interrupt
0 => Disable GPIO1 for Detection interrupt
1 => Enable GPIO1 for Detection interrupt
Note: This programmability is valid only if D11 and D9 of control register 23H/page 2 are set to
0

R/W
Enable GPIO2 for CLKOUT
0 => Disable GPIO2 for CLKOUT mode.
1 => Enable GPIO2 for CLKOUT mode.
In CLKOUT mode the frequency of output signal is equal to the 256xDAC_FS if DAC_FS is faster
than ADC_FS otherwise equal to the 256xADC_FS.
Note: This programmability is valid only if PLL is enabled, D15 and D13 of register 23H/page 2
are set to 0 and GPIO2 is not enabled for detection interrupt.

ADWS Selection
0X => GPIO1 pin output is tristated.
10 => GPIO1 pin acts as button press detect interrupt.
11 => GPIO1 pin acts as ADC wordselect (ADWS).
Note: 1. This programmability is valid only if D11 and D9 of control register 23H/page 2 are set
to 0.
2. These bits should be programmed ‘11’ only if different ADC and DAC sample rates are desired.
In this mode WCLK acts as DAWS i.e. DAC sample rate and GPIO1 acts as ADWS i.e. ADC
sample rate.
