Description
Audio Bit Clock. The serial bit clock from the codec.
Note:
Serial Data Output. This output transmits audio serial
data to the codec.
Serial Data Input. This input receives serial data from
the primary codec.
Note:
Serial Data Input 2. This input receives serial data from
the secondary codec. This signal has wakeup capability.
Serial Bus Synchronization. This bit is asserted to syn-
chronize the transfer of data between the SC1200/
SC1201 processor and the AC97 codec.
Codec Clock. It is twice the frequency of the Audio Bit
Clock.
Codec Reset. S3 to S5 wakeup is not supported
because AC97_RST# is powered by V
states S3 to S5 are needed, a circuit in the system board
should be used to reset the AC97 codec.
PC Beep. Legacy PC/AT speaker output.
Description
32.768 KHz Output Clock
General Purpose Wakeup I/Os. These signals each
have an internal pull-up of 100 KΩ.
LED Control. Drives an externally connected LED (on,
off or a 1 Hz blink). Sleeping / Working indicator. This sig-
nal is an open-drain output.
On / Off Control. This signal indicates to the main power
supply that power should be turned on. This signal is an
open-drain output.
If selected as BIT_CLK function but not used, tie
BIT_CLK low.
If selected as SDATA_IN function but not used,
tie SDATA_IN low.
