Hello,I can't find the "xtal and extal" pin in MKM33Z128ACLH5 (64-pin LQFP), is there somebody can tell me how to finish the external crystal connection. thanks very much!
According to DataSheet and Reference Manual and bxl file, didn't find this MCU have XTAL and EXTAL pins.
You may need to connect crystal at XTAL32K and EXTAL32K pins.

But the XTAL32K and EXTAL32K pins are for RTC oscillator, and the XTAL and EXTAL pins are for system oscillator.
Yes. You are right.
There are no crystal pins for system oscillator in this MCU. And you may need to use IRC or RTC oscillator for the MCG clock source.
