/*    Function:      Init_all
 *
 *    This function is used to initialize the peripherals.  SFR Value Entries in the sfrs[]
 *    array are filled in by ApBUILDER at code-generation time.
 *    This function takes those entries and passes them to the various general-purpose initialization
 *    routines.
 *
 *    While this is inefficient, it is coded this way for clarity, and for educational purposes.
 *    The initialization routines are also inefficient, as they must handle 'every' case presented
 *    to them.  You will probably want to eliminate unnecessary parameter passing, and unnecessary
 *    code from your final program.  You will also find that you can combine functionality from
 *    several initialization routines to make one single efficient init routine.
 *    Again, it has been seperated and expanded here for the purpose of clarity (showing which SFR's
 *    are involved for each peripheral), and to handle each possible case.
 *
 *    In the Timer section below, you will see that TIMER1 will be set up to provide a heart-beat
 *    tick at 10ms for the TCB functionality if the compiler directive is switched on.  You will
 *    need to fill in TL1 and TH1 with correct values to acheive 10ms overflow rate.  These values
 *    will be dependent on your clock speed.  They are not set by ApBUILDER.
