标题: RK1808 I2S0
RK1808上的I2S0引脚不是双向的，它分为数据输入和数据输出。我们需要联系两件事：PDM麦克风阵列和我们的I2S音频输出处理器。

EVB原理图包括用于“MIC阵列 - 数字接口”的连接器。 EVB的手册列出了连接器，但没有说明它是如何工作的。

如果这些引脚用于PDM话筒......
I2S0_SDI0，I2S0_SDI1，I2S0_SDI2，I2S0_SDI3，PDM_CLK0，PDM_CLK1

I2S0输出可以与外部I2S编解码器一起使用吗？
IS20_SDO0 / 3，I2S0_MCLK，I2S0_LRCLK_TX，I2S0_SCLK_TX

PDM麦克风输入单元是否独立于IS20输出？
它们可以同时使用并以不同的时钟速率运行吗？

------------------------------------

I2S0 pins on the RK1808 are not bidirectional, it is split into datain and data out. So we need to hook up two things: PDM mic array andour I2S audio output processor.

The EVB schematic includes a connector for a "MIC Array -DigitalInterface". The manual for the EVB lists the connector but doesn't say anything about how it works.

If these pins are being used for PDM mics...
I2S0_SDI0, I2S0_SDI1, I2S0_SDI2, I2S0_SDI3, PDM_CLK0, PDM_CLK1

Can I2S0 output be simultaneously used with external I2S codec?IS20_SDO0/3, I2S0_MCLK, I2S0_LRCLK_TX, I2S0_SCLK_TX
Is the PDM microphone input unit independent of IS20 output?
Is the PDM mic input unit independent of IS20 output? Can they beused simultaneously and be running at different clock rates?
