Hi ... have code that outputs I2S in master mode. The slave, a NAU8822 device requires Master Clock Source between 8 and 33MHz.
The 54L MCLK pin is duplicating the BCLK frequency, currently 1,2MHz odd. Datasheet for 54L Series, page 324 says ..
Example: NRF_I2S->CONFIG.RATIO = I2S_CONFIG_RATIO_RATIO_256X << I2S_CONFIG_RATIO_RATIO_Pos;
The issue however is that the SDK uses a i2c_config struct for setting up the I2S. No option exists to set the divide ratio.
No examples or test example code seem to show a solution for this.
Can you please assist in how I can set the divide ratio for the MCLK.
Thank you
Brian
