Note*: These capacitor values are for design guidance only. The recommended 32K XTAL features are ESR=11.2~35K and CL1=CL2 =20~30pF (including

PCB parasitic loading, for example, user should apply additional 14~24pF on X32I and X32O if PCB parasitic loading is 6pF)

Note: VDD33_REG is output of built-in regulator with maximum current 60 mA. It is recommended that only use it for internal power pad.
