Get Parameter Command Format:
Bits [19:16] = ‘Bh’, where bits [15:0] are defined below:
Bits Type Default Description
31:30 Read/Write 00b
Port Connectivity (PCON): The port complex is
connected to a jack.
29:24 Read/Write 000001b
Location (LOC): This field indicates the physical
location of the jack or device to which the pin
complex is connected. Set to External | Rear.
23:20 Read/Write Ah
Default Device (DD): Indicates the intended use
of the connection is for Mic In.
19:16 Read/Write 1h
Connection Type (CTYP): Indicates the type of
physical connection is 1/8” jack.
15:12 Read/Write 9h
Color (COL): This field indicates the color of the
physical jack for use by software. The color
selected is Pink.
11:8 Read/Write 0h
Miscellaneous (MISC): No PDC override.
7:4 Read/Write 3h
Default Association (DA): This field is used by
software to group Pin Complex (and therefore
jacks) together into functional blocks to support
multichannel operation. All jacks with the same
association number may be assumed to be
grouped together. A value of all ‘0’s is reserved.
A value of all ‘1’s in this field indicates that the
Association has the lowest priority.
3:0 Read/Write 1h
Sequence (SEQ): This field indicates the order
of the jacks in the association group.

Bits [15:0] Value Description
15 0b
Get Output/Input (GOI): This bit controls whether the request is for the
input amplifier or the output amplifier. When ‘1’, the output amplifier is
being requested. When ‘0’, the input amplifier is being requested.
14 0b ‘0’b
13 xb
Get Left/Right (GLR): This bit controls whether the request is for the
left channel amplifier or the right channel amplifier. When ‘1’, the left
channel amplifier is being requested. When ‘0’, the right channel ampli-
fier is being requested.
12:4 000000000b Reserved
3:0 0000b
Index (IDX): This field specifies the input index of the amplifier setting
to return if the widget has multiple input amplifiers. This field has no
meaning and ignored since the widget does not have multiple input
amplifiers. It should be always ‘0’s.
