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.
