(hi-z) when read. 2.1.3. jack detect plugs inserted to a jack on ports a, b, c & spdifout0 are detected using sense_a. plugs inserted to a jack on ports e,f, dmic0, & spdifout1 are detect ed using sense_b. per hda015-b, the detection circuit operates when the codec is in d0 - d3 and can also operate if both the codec and controller are in d3 (no bus clock.) jack dete ction requires that all supplies (analog and digital) are active and stable. when avdd is not present, the value reported in the pin widget is invalid. afg power state input enable output enable port behavior d0-d2 1 1 not allowed. port is active as output. input path is mute. 1 0 active - port enabled as input 0 1 active - port enabled as output 0 0 inactive -port is powered on (low output impedance) but drives silence only. d3 - 0 inactive (lower power) - port keeps output coupling caps charged if port uses caps. - 1 low power state. if enabled, beep will output from the port d3cold - - inactive (lower power) - port keeps output coupling caps charged if port uses caps. d4 - - inactive (lower power) - port keeps output coupling caps charged if port uses caps. d5 - - off - charge on coupling caps (if used) will not be maintained. table 2. analog output port behavior

(wlp 3.09 - please refer to the latest windows logo program requirements from microsoft.) the capless headphone drivers are supplied with +/-2.5v derived from avdd. therefore, it is possi- ble to run the headphone supply from 5v and maintain ~60mw peak output power into 32 ohm headphones. head phone performance will degrade if more than one po rt is driving a 32 ohm load.

(parts may be ordered with the regulator disabled). the regulator uses pin 9, dvdd, as its voltage source. the output of the ldo is connected to pin 1 and the digital core. a 10uf capacitor mu st be placed on pin 1 for proper lo ad regulation and regulator stability. the digital core voltage regulator is only dependent on dvdd. dvddio may be either 3.3 or 1.5v and may proceed or follow dvdd in sequence. the codec digital logic and i/o (unless referenced to avdd) will operate in the absen ce of avdd. dvdd and avdd supp ly sequencing for the applica- tion of power and the removal of power is neither defined nor guaranteed. it is common for desktop systems to supply avdd from the system standb y supply and the codec will tolerate, indefinitely, the condition where avdd is active but dvdd and dvddio are inactive. to prevent pops, software is expected to mute pa ths as close to the port as is possible when chang- ing power states or signal topology.
