Function

Default

0x09

Mono headset (mono speaker left channel and mic. Read Functions 5 and 6 for

matching microphone)

0x0A

Allows a vendor to report sensing other type of devices/peripherals. SR [5:0]

together with OR [1:0] provide information regarding the type of device sensed

0x0B–0x0E

Reserved

0x0F

Unknown (use fingerprint)

0x10–0x1F

Reserved

S [4:0] (RO)

Sensed bits (when input sense cycle initiated). This field allows for the reporting of the type of input peripheral/device

plugged in the jack. Specified values should be interrogated with the SR [5:0] and OR [1:0] bits for accurate reporting.

ST [2:0]

Sense Value

0x10

Data not valid. Indicates that the reported value(s) is invalid

0x11

No connection. Indicates that there are no connected devices

Default

0x12

Indicates a specific fingerprint value for devices that are not specified or are

unknown

0x13

(Connector/Jack

location Bits,

Read/Write)

This field describes the location of the jack in the system. This field is updated by the BIOS. These bits are only reset by a

power-on reset because it is typically written by the system BIOS and is not reset by codec hard or soft resets as long as

power remains applied to the codec.
