Features: For ADAU1452 series routines, the configuration page can freely choose the communication mode (SPI or I2C) between SIGMASTUDIO and the targets board. The SPI address is SPI 0x1 ADR0, and the I2C address is: I2C 0x16 (118), E2Prom are SPI 0x1 ADR0, do not need to change. USBi and targets board (ADAU1452dsp board) link mode definition: SPI communication mode: 1/3/5/7/9(CLK/CS/MISO/MOSI/GND) at the USBi end of the emulator corresponds to 5/4/3/2/1 of the targets board (ADAU1452dsp board) CN2 respectively. Just in order. I2C communication mode: 2/4/6 (GND/SCL/SDA) on the USBi end of the emulator corresponds to 1/5/3 of CN2 on the targets board (ADAU1452dsp board) respectively.
