Table 18: Pin Definition of I2C Interfaces
4.7. I2S Interfaces
The module provides two I2S interfaces, which are low-power I2S. Data signals of both interfaces can be
configured as input or output, and the reference power domain of the interfaces is 1.8 V. LPI_MI2S0
interface is multiplexed from DMIC interface
