**     Filename  : RTC1.C
**     Project   : rtc
**     Processor : MC9S08JM60CLHE
**     Component : Init_RTC
**     Version   : Component 01.017, Driver 01.09, CPU db: 3.00.046
**     Compiler  : CodeWarrior HCS08 C Compiler
**     Date/Time : 2010-1-9, 20:41
**     Abstract  :
**          This file implements the API (RTC) module 
**          initialization according to the Peripheral Initialization 
**          Bean settings, and defines interrupt service routines prototypes.
**          The Autonomous periodical Interrupt module can generate
**          periodical interrupts independent of the clock source of 
**          the MCU. To enable the timer, the bit APIFE needs to be 
**          set. The API timer is either clocked by a trimmable 
**          internal RC oscillator or the bus clock. Timer operation
**          will freeze when MCU clock source is selected and bus clock 
**          is turned off. The clock source can be selected with bit
**          APICLK. As soon as the configured timeout period of the API 
**          has elapsed, the APIF bit is set. An interrupt, indicated by 
**          flag APIF = 1, is triggered if interrupt enable bit APIE = 1.
**     Settings  :
**          Bean name                                      : RTC1
