REAL TIME CLOCK (RTC) 

This chapter describes the functions and usage of Real Time Clock (RTC) in S3C2416 RISC microprocessor. 

     

1 OVERVIEW 

The Real Time Clock (RTC) unit can be operated by the backup battery when the system power is off. The data 

include the time by second, minute, hour, date, day, month, and year. The RTC unit works with an external 32.768 

KHz crystal and can perform the alarm function.  

 

1.1 FEATURES 

The Real Time Clock includes the following features: 

•

  BCD number: second, minute, hour, date, day, month, and year. 

•

  Leap year generator 

•

  Alarm function: alarm-interrupt or wake-up from power-off mode. 

•

  Tick counter function: tick-interrupt or wake-up from power-off mode. 

•

  Year 2000 problem is removed. 

•

  Independent power pin (RTCVDD). 

•

  Supports millisecond tick time interrupt for RTOS kernel time tick.
