RTC calibration in LPC55S69

[gnichimohamed]

Hello,

In the LPC55S69 there is no mentioning of RTC calibration, do you have any idea how we can do it?

Thanks for the help!

Hello gnichimohamed,

Sorry LPC55s69 doesn't support RTC calibration. 

32-bit Real-time clock (RTC) with 1 s resolution running in the always-on power
domain. A timer in the RTC can be used for wake-up from all low power modes
including deep power-down, with 1 ms resolution. The RTC is clocked by the
32 kHz FRO or 32.768 kHz external crystal.
