LPC1766 RTC.

The RTC is a set of counters for measuring time when system power is on, and optionally
when it is off. The RTC on the LPC1768/66/65/64 is designed to have extremely low
power consumption, i.e. less than 1 mA. The RTC will typically run from the main chip
power supply, conserving battery power while the rest of the device is powered up. When
operating from a battery, the RTC will continue working down to 2.1 V. Battery power can
be provided from a standard 3 V Lithium button cell.
An ultra-low power 32 kHz oscillator will provide a 1 Hz clock to the time counting portion
of the RTC, moving most of the power consumption out of the time counting function.
The RTC includes a calibration mechanism to allow fine-tuning the count rate in a way that
will provide less than 1 second per day error when operated at a constant voltage and
temperature. A clock output function (see Section 7.29.4) makes measuring the oscillator
rate easy and accurate.
