Detailed Description

NXT system clock related class.

[ How to use with TOPPERS/ATK1(OSEK) ]
I2C (derived/compositted) class and Clock class internally use RTOS features. Thus, user needs to implement a C function and RTOS provided events.

+ Invoke SleeperMonitor function in user_1msec_isr_type2 hook.
  void user_1ms_isr_type2(void)
  {
    SleeperMonitor(); // needed for I2C devices and Clock class
  }

+ Define EventSleepI2C and EventSleep Events in user oil file.
  EVENT EventSleepI2C
  {
    MASK = AUTO;
  };

  EVENT EventSleep
  {
    MASK = AUTO;
  };

  TASK TaskMain
  {
    AUTOSTART = TRUE
    {
      APPMODE = appmode1;
    };
    PRIORITY = 1;
    ACTIVATION = 1;
    SCHEDULE = FULL;
    STACKSIZE = 512;
    EVENT = EventSleepI2C; <- Here it is
    EVENT = EventSleep; <- Here it is
  };

[ How to use with TOPPERS/JSP(ITRON) ]
In case of using this class with TOPPERS/JSP(ITRON), RTOS specific definitions for the class are not needed.
