AFE4300: AFE4300 doesn't get clock

Hello,

The applications engineer supporting this device is currently on a business trip.
Please post your questions to the email list biosensing_afe-support@list.ti.com along with a reference to this E2E post.

BTW what is the status of the reset signal? Is it logic high?
Have you configured the registers?
Some register bits need to be written after power up and reset for proper operation. Refer to the datasheet for details.

There is no problem reading and writing registers. It read the same value as the one I wrote.

Here is the value that I write to AFE4300.

AFE4300_SPI_Write(AFE4300_ADC_CONTROL1, 0x4140);
AFE4300_SPI_Write(AFE4300_MISC1, 0x0000);
AFE4300_SPI_Write(AFE4300_MISC2, 0xFFFF);
AFE4300_SPI_Write(AFE4300_WEIGHT_SCALE_CONTROL, 0x0000);
AFE4300_SPI_Write(AFE4300_BCM_DAC, 0x0040);
AFE4300_SPI_Write(AFE4300_DEVICE_CONTROL2, 0x0000);
AFE4300_SPI_Write(AFE4300_MISC3, 0x00C0);

AFE4300_SPI_Write(AFE4300_DEVICE_CONTROL1, 0x6006);
AFE4300_SPI_Write(AFE4300_VSENSE_MUX, 0x0408);
AFE4300_SPI_Write(AFE4300_ISW_MUX, 0x0408);
AFE4300_SPI_Write(AFE4300_IQ_MODE, 0x0000);
AFE4300_SPI_Write(AFE4300_ADC_CONTROL2, 0x0063);

I didn't read register since it reads register well.

I think there's no problem with setting registers.
