Keywords:i.MX25? real time clock? ARM core? digital clock?

This application note describes how to initialize and maintain the real time clock (RTC) on the i.MX25. The RTC is a digital clock which can be used to accurately keep track of the current time. Some benefits of having an embedded real time clock include:
?? Low power consumption (since the RTC on the i.MX25 can run from a coin cell battery)
?? Frees the ARM core to do tasks other than time keeping
?? Continues to keep time even while the i.MX25 is powered down

This application note is intended for non-security customers with non-secure devices.
