1、 Please reserve bypass cap near AP when using AUX_ADC pin for decouple noise. The bypass cap value depends on the frequency of the noise, shown as below
–For decouple low frequency noise, please reserve 100nF bypass cap
–For decouple RF noise, please reserve 100pF bypass cap
2、If AUX_ADC port is used as GPI or EINT function, please also reserve C0402/C0201 footprint near AP for bypass cap. (Default: NC)
3、When the AUXADC is not used, please connected to ground. (Avoid de-sense issue)
