28 / 52 page ![]() SSM4567 Data Sheet Rev. 0| Page 28 of 52 TYPICAL APPLICATION CIRCUITS SOFTWARE CONTROL MODE, I2S/TDM INTERFACE Figure 54. Typical Application Circuit, I2S, Software Control Mode Description In this application circuit, the SSM4567 is controlled by an external master on the I2C interface. The I2C address is configured using the LR_SEL/ADDR pin. The serial data interface is in PCM mode, as configured by the SEL pin. Pin Configuration Table 21. Pin Configuration for I2S Software Control Applications, Software Control Mode, I2S/TDM Interface Hardware Pin Connection LR_SEL/ADDR Connect to AGND for I2C Address 0x34; IOVDD for I2C Address 0x35; leave open for I2C Address 0x36. SEL Connect to IOVDD for PCM mode. SNS_PDM_CLK/FSYNC Connect to an external I2S/TDM frame sync clock signal. DAC_PDM_CLK/BCLK Connect to an external I2S/TDM bit clock signal. SNS_PDM_DAT/SNS_SDATAO Sends current, voltage, and battery sense data in I2S/TDM format to an external IC. DAC_PDM_DAT/DAC_SDATAI Receives a serial audio data signal in I2S/TDM format from an external IC. SCL Connect to the clock signal of an external I2C master IC. SDA Connect to data signal of an external I2C master IC.
