Description
Audio Controller Sync. This is a 48 kHz sync pulse that signifies the
beginning of a serial transfer on AC_S_OUT, AC_S_IN, and AC_S_IN2.
AC_S_SYNC is synchronous to the rising edge of AC_CLK. Connect to
the audio codec’s SYNC pin.
Boot Options Select Bit 0. During system reset, this ball is the LSB of
the 2-bit boot option (balls L2 and L3), used to determine the location of
the system boot device. It should be pulled low if required by Table 3-5
"Boot Options Selection" on page 34, otherwise, an internal pull up,
asserted during reset, will pull it high. During reset, the ball drivers are
held in TRI-STATE mode, and the ball is sampled on the rising edge of
RESET_OUT# (i.e., when external reset is de-asserted). After reset, this
signal defaults low (off).
Legacy PC/AT Speaker Beep. Connect to codec’s PC_BEEP.
This function is only available when GPIO1 is programmed to
OUT_AUX1. See Table 3-8 "GPIO Options" on page 47.
Audio Controller Serial Data Input 2. This input receives serial data
from a second codec. This data stream contains both control data and
ADC audio data. This input data is sampled on the falling edge of
AC_CLK. If the codec’s Ready bit is set in this stream (slot 0, bit 15), then
it is functionally ORed with AC_S_IN.
Connect to a second codec’s serial data output.
This function is only available when GPIO12 is programmed to IN_AUX1.
See Table 3-8 "GPIO Options" on page 47.
