That is a misunderstanding, they are marked as type "analog input", but they can only serve for a 32768Hz crystal or oscillator input, see section

5.4.2.4 32.768 kHz crystal oscillator (LFXO)

of the product specification. No link with ADC.

I was asked to use XL1 pin and XL2 as inputs for the saadc. Can that be done??

Thanks Again have a nice day.

Peter is absolutely correct. The analog pins AIN0, AIN1, AIN5, and AIN7 are not included in the QFN32 package. You'll have to use the QFN48 package if you need more than the four analog inputs included in the QFN32 package.

Best regards,

Simon

Well, the pins marked AIN2/AIN3/AIN4/AIN6 have an analog function. Given the numbering, the other AIN pins are not available in this package.
