hi
I have a problem while developing AFE4300.
The Vref pin is always zero and MCU provide the 1MHz clock by PWM.
register settings cannot be read any back.
I think the afe4300 is not work.
here is the register values
AFE4300_WRITE(AFE4300_REGISTER_DEVICE_CONTROL1,0x6006);
AFE4300_WRITE(AFE4300_REGISTER_ADC_CONTROL_REGISTER1,0x4140);
AFE4300_WRITE(AFE4300_REGISTER_DEVICE_CONTROL2,0x0000);
AFE4300_WRITE(AFE4300_REGISTER_ADC_CONTROL_REGISTER2,0x0063);
AFE4300_WRITE(AFE4300_REGISTER_BCM_DAC_FREQ,0x0034);
AFE4300_WRITE(AFE4300_REGISTER_ADC_CONTROL_REGISTER1,0x4140);
AFE4300_WRITE(AFE4300_REGISTER_DEVICE_CONTROL2,0x0000);
AFE4300_WRITE(AFE4300_REGISTER_ADC_CONTROL_REGISTER2,0x0063);
AFE4300_WRITE(AFE4300_REGISTER_BCM_DAC_FREQ,0x0034);
AFE4300_WRITE(AFE4300_REGISTER_IQ_MODE_ENABLE,0x0000);
AFE4300_WRITE(AFE4300_REGISTER_MISC_REGISTER1,0x0000);
AFE4300_WRITE(AFE4300_REGISTER_MISC_REGISTER2,0xFFFF);
AFE4300_WRITE(AFE4300_REGISTER_MISC_REGISTER3,0x0030);
AFE4300_WRITE(AFE4300_REGISTER_MISC_REGISTER1,0x0000);
AFE4300_WRITE(AFE4300_REGISTER_MISC_REGISTER2,0xFFFF);
AFE4300_WRITE(AFE4300_REGISTER_MISC_REGISTER3,0x0030);
AFE4300_WRITE(AFE4300_REGISTER_ISW_MUX,0x0408);
AFE4300_WRITE(AFE4300_REGISTER_VSENSE_MUX ,0x0408);
AFE4300_WRITE(AFE4300_REGISTER_VSENSE_MUX ,0x0408);
Thanks for your help.
