According to page 87,88,90 in SPRS582B, C6457 I2C interface Voltage should be 1.8V. This means SDA and SCLK should be pulled up to 1.8V with 4.7K resistor. But on page 12 in schematic_C6457evm_r01b4.pdf, these two pins are pulled up to 3.3V with 4.7K resistor. I'm puzzled by the confliction. Any one has practical experirence with C6457 I2C interface ?
