49 / 112 page  12.0 Status & Control Registers (Continued) 12.28 DETECT CONFIGURATION REGISTER This register is used to control the headset detection system. TABLE 29. DETECT (0x17h) Bits Field Description 0 DET_INT If set an IRQ is raised when a change is detected in the headset status. Clearing this bit will clear an IRQ that has been triggered by the headset detect. 1 BTN_INT If set an IRQ is raised when the headset button is pressed. Clearing this bit will clear an IRQ that has been triggered by a button event. 2 TEMP_INT If set an IRQ is raised during a temperature event. If cleared, the LM4935 will still automatically cycle the power amplifiers off if the internal temperature is too high. This bit should not be set whenever the loudspeaker amplifier is turned on. Clearing this bit will clear an IRQ that has been triggered by a temperature event. 6:3 HS_ DBNC_TIME Sets the time used for debouncing the analog signals from the detection inputs used to sense the insertion/removal of a headset.
