D Headset Detection
Interrupt polarity: Active high.
Typical interrupt duration: 1.75 ms.
Debounce programmability on bits D10 and D9 in control register 22H/Page 2:
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)
Headset detect flag is available till headset is connected.
D Button Detection
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
Debounce programmability:
00 => No glitch rejection
01 => 8 ms duration (with 1 ms clock resolution)
10 => 16 ms duration (with 2 ms clock resolution)
11 => 32 ms duration (with 4 ms clock resolution)
Button detect flag is set when button is pressed. It gets clear when flag read is done after button press
removal.
AUDIO ROUTING
Audio Interface for Smart-Phone Applications
The TSC2101 supports audio routing features to combine various analog inputs and route them to analog
outputs or the ADC for smartphone applications. In smart-phone applications, the TSC2101 can be used to
interface the cell-phone module to microphones and speakers. The TSC2101 allows the input from the
cell-phone module to be routed to different speakers through a PGA which supports a range of 12 dB to –34.5
dB in steps of 0.5 dB. The cell-phone input can also be mixed with the microphone input for recording through
the ADC. The microphone or DAC audio can be routed to the cell-phone output. The buzzer input from
cell-phone can be routed to the speakers through a PGA. The buzzer input supports PGA range of 0 dB to –45
dB in steps of 3 dB. The mixing and PGA are under full software control. The mixing feature can be used even
when both ADC and DAC are powered down. Cell-phone PGA, microphone PGA and buzzer PGA includes
soft-stepping logic. Soft-stepping logic works on Fsref if DAC is powered up otherwise; it works on internal
oscillator clocks.
