Part Number: TMS320F28335 Hi Expert, Customer met a problem that the ADCTRL3 content should be written as 0x00E7, however after run through the configuration code, The AdcRegs.ADCTRL3.all = 0x0007. ADC unit could not power up. There are 50% boards existing this kind of issue. Customer configured the ADCENCLK = 1 & ADC_cal() twice as the code in F28335 ADC example. If delete one of the "SysCtrlRegs.PCLKCR0.bit.ADCENCLK =1", the issue is solved. The CPU core voltage is 1.9V and ADC reference voltage is 2.048V. Could you give some advice on the issue or what we should do to debug it? Thanks! The ADC configuration codes. The ADC power circuit. The CPU core(channel 1) and ADC reference voltage(channel 2) power up waves. Best Regards Rayna Wang
