D Auto Detection
The TSC2101 has built in monitors to automatically detect the insertion and removal of headsets. The detection
scheme can differentiate between stereo, cellular and stereo-cellular headsets. Upon detection of headset
insertion or removal, the TSC2101 updates read-only bit D12 of control register 22H/Page 2. The TSC2101 can
be programmed to send an active high interrupt for insertion and removal of headsets to the host-processor
over GPIO1 using bit D3 of control register 22H/Page 2 and GPIO2 using bit D4 of control register 22H/Page
2. The headset detection feature can be enabled by setting bit D15 of control register 22H/Page 2. When
headset detection is enabled and headset is not detected, SPK1, VGND and MICBIAS_HED are turned off
irrespective of control register settings. The TSC2101 also has the capability to detect button press on the
headset microphone. It consumes less than 50 A while waiting for button press with everything else powered
down. Upon button press, the TSC2101 updates read-only bit D11 of control register 22H/Page 2. It can also
send an active high interrupt for indicating button press to the processor over GPIO1 using bit D1D0 of control
register 22H/Page 2. The TSC2101 provides debounce programmability for headset and button detect.
Debounce programmability can be used to reject glitches generated, and hence avoids false detection, while
inserting headset or pressing button.
Figure 24 shows terminal connections and jack configuration required for various headsets. Care should be
taken to avoid any dc path from MIC_DETECT_IN to ground, when a headset is not inserted.
