What is the function of AVDDCP capacitance and C+/C- capacitance and, can it be omitted?
AVDDCP and C+/C- capacitors are Charge pump capacitor needed when boost,
When the system needs to start Charge pump - that is need to boost case, for example, VDD = 3V, the capacitor can not be ignored.
When the system do not need to start Charge pump- that is not need to boost case, for example, VDD = 5V, the capacitor can be ignored
