IO-T
Music DAC Serial Data Output
This signal is the serial bit stream used to transmit PCM data to a
industry standard serial DAC. Any mono or stereo PCM audio
stream can be played from the DSP to this interface to provide
music without the need for an AC’97 codec.
If the serial port is disabled, then this pin can be used for general
purpose I/O control.
MCLK
158
IO-T
Music DAC Data Bit Clock
The MSI data is synchronized to this clock used by an external
Music DAC.
If the serial port is disabled, then this pin can be used for general
purpose I/O control.
MLRCK
159
IO-T
Music DAC Data Word Clock
This signal is used to frame the left and right channel PCM data
being transmitted to the external Music DAC.
If the serial port is disabled, then this pin can be used for general
purpose I/O control.
