2.9 Audio interface

The FRWY-LS1012A board supports 3.5mm jack for audio and mic interface using the

SGTL5000 codec. This codec connects with LS1012A on the SAI2 interface.

SAI2 supports full duplex audio and takes bit clock (TX and RX BCLK) and frame clock

(TX and RX SYNC) as input from SGTL5000. The SGTL5000 generates these clocks

based on a 25 MHz MCLK, which is fed from the 25 MHz crystal clock. The SGTL5000

control interface is I2C-based and can be accessed at the 0x0A address.
