For one Pin, Digital input and analog input as 2 Channel.

Not sure if I understood that. The ADC uses some time to do the conversion. You can't switch the input during this time.

Do you know in the following?

3) Is it possible to perform SAADC while switching 2 analog analog input (from Analog Multiplexer) for one Pin?

Thanks for your answer.

Is the register that enables the ADC specifically in the following?

ENABLE
Address offset: 0x500
(Enable or disable ADC)

You can re-define a pin between digital and analog input. The ANAEN signal comes from the ADC when it's enabled, see this register. So the pin becomes AIN only when the ADC is enabled, else it's what's defined as in the PIN_CNF register.

You might find it easier to use a I2C port extender if you're short of pins.
