Figure 8: Timing in Primary Mode

In auxiliary mode, the data is sampled on the falling edge of the PCM_CLK and transmitted on the rising

edge. The PCM_SYNC rising edge represents the MSB. In this mode, the PCM interface operates with a

256kHz, 512kHz, 1024kHz or 2048kHz PCM_CLK and an 8kHz, 50% duty cycle PCM_SYNC. The

following figure shows the timing relationship in auxiliary mode with 8kHz PCM_SYNC and 256kHz

PCM_CLK.

Figure 9: Timing in Auxiliary Mode

Clock and mode can be configured by AT command, and the default configuration is master mode using

short frame synchronization format with 2048kHz PCM_CLK and 8kHz PCM_SYNC. In addition, EC21
Mini PCIe’s firmware has integrated the configuration on some PCM codec’s application with I2C interface.
