7.16 Real Time Clock:

Real time clock function is available with the timer RE and it generates one sec-

ond signals. When the timer RE is configured for this mode, timer gets the re-

quired clock signal from the externally connected crystal of 32.768 KHz. The

required one second signal is generated through a set of dividing registers and is

fed to next level of registers to track other timing parameters like minutes, hours

and week.

This RTC generates timing information in both 12

and 24 hour formats. If required, an interrupt can

also be generated at the rate of one second,

minute, hour and so on.
