S32K322 RTC

Hi,

I'm Using the S32K322 100 Pin HDQFP microcontroller. In the reference manual pins 15 and 17 are mentioned external crystal. I plan to use an external 24MHz crystal in those pins for the fast clock. Could you please mention which pins are the external RTC crystal (32.768KHz) in the S32K322?

Hi @Chinnan

The SXOSC crystal pins (OSC32K_XTAL and OSC32K_EXTAL) for S32K322 100 Pin HDQFP are unavailable (refer to attached image).

For more details on pin functionality, refer to S32K342_S32K341_S32K322_IOMUX.xlsx attached to the reference manual.
