Dear all, I have 1758 microcontroller with 80 pinout.

I need to calibrate the RTC, but in the 80 pin package, the P1.27 CLKOUT it isn't present .!

How can I calbrate it ?

Thanks

Hi Stefano De Blasiis ,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
If you want to validate the RT oscillator works well, the oscilloscope is an option to validate RTC oscillator directly, which provides a visualize wave and a variety of measurements.

Have a great day,

Hi Stefano De Blasiis ,

Thank you reply.
As I mentioned before, the oscilloscope can connect the RTC oscillator directly to validate the RT oscillator works well.
