User manual
The RTC is configured using the following registers:
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 LPC17xx, 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, which can be connected to a battery,
externally tied to a 3V supply, or left floating.
The RTC power domain is shown in conceptual form in
time keeping portion of the RTC is shown in
1. Power: In the PCONP register
2. Clock: The RTC uses the 1 Hz clock output from the RTC oscillator as the only clock

the NVIC using the appropriate Interrupt Set Enable register.
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 microamp
required for battery operation. Uses power from the CPU power supply when it is
present.
20 bytes of Battery-backed storage and RTC operation when power is removed from
the CPU.
Dedicated 32 kHz ultra low power oscillator.
Dedicated battery power supply pin.
RTC power supply is isolated from the rest of the chip.
Calibration counter allows adjustment to better than ±1 sec/day with 1 sec resolution.
Periodic interrupts can be generated from increments of any field of the time registers
and selected fractional second values.
Alarm interrupt can be generated for a specific date/time.
