We have gone through the SAM D5x/E5x Family datasheet and ASF4 API Reference Manual. Using Atmel Start , we have configured the SAMD51 pins to respective module (ADC,DAC,SPI). We have below query regarding clock configuration.
We are planning to use ADC 0 , ADC 1 , DAC 0 , SPI 0 , Timer 0, I2C 0 software components in SAMD51. We have not connected any external crystal oscillator to SAMD51.
Is it possible to use only internal clock (32.768 KHz) for entire system ( CPU,ADC0,ADC1,DAC0,SPI0,I2C0) ? Will it be sufficient?
Also, is it possible to change the configuration later after creating project with start configurator?
