55 / 156 page ![]() ALC5642-VF Datasheet Multi-Channel Audio Hub/CODEC with embedded Voice DSP and SounzReal TM Digital Sound Effect 43 Rev. 0.93 For IRQ function as shown at Figure 24, the IRQ output source can be selected from JD Status, JD2 Status, Over-Temperature Status and MICBIAS1 Over-Current Status. When either status is trigged, the GPIO will output a flag as interrupt signal. sta_jd_internal(MX-BF[4]) IRQ MX-BD[11] MX-BD[15] ovt_status(MX-BF[3]) MX-BD[10] MX-BD[14] ovc_micbias1(MX-BE[3]) MX-BE[7] MX-BE[15] Sticky Control MX-BD[13] Sticky Control MX-BD[12] Sticky Control MX-BE[11] Sta_jd2_internal(MX-FB[11]) MX-FB[10] Sticky Control MX-FB[9] MX-FB[11] Figure 25. IRQ Function Block In general, the IRQ output needs to combine with JD function. When JD is trigger, IRQ will output a flag to host to notice S/W driver. The S/W driver will do something by system design. The behavior flow chard as following: Device Plug-In JD Triggered Initial Settings (For JD and IRQ) IRQ Flag Output to Host S/W Driver Settings Clear JD Status for Next JD Trigger |
