The Real Time Clock (RTC) is a set of counters for measuring time when system power is
on, and optionally when it is off. It uses very little power when its registers are not being
accessed by the CPU, especially reduced power modes. On the LPC4350/30/20/10, the
RTC is clocked by a separate 32 kHz oscillator that produces a 1 Hz internal time
reference. The RTC is powered by its own power supply pin, VBAT.

Measures the passage of time to maintain a calendar and clock. Provides seconds,
minutes, hours, day of month, month, year, day of week, and day of year.
Ultra-low power design to support battery powered systems. Less than 1 μA required
for battery operation. Uses power from the CPU power supply when it is present.
