#INT_TIMER0
Timer0_Interrupt( )
{
   ......
}
void main( )
{
   ......
   enable_interrupts(INT_TIMER0);
   enable_interrupts(GLOBAL);
   ......
}





设置初值
see help file
Syntax: set_timer0(value)     or   set_rtcc (value)
set_timer1(value)
set_timer2(value)
set_timer3(value)
Parameters: Timers 1 and 3 get a 16 bit int.
Timer 2 gets an 8 bit int.
Timer 0 (AKA RTCC) gets an 8 bit int except on the PIC18XXX where it needs a 16 bit int.
Returns: undefined
Function: Sets the count value of a real time clock/counter.  RTCC and Timer0 are the same.  
All timers count up.  When a timer reaches the maximum value it will flip over to 0 and continue counting (254, 255, 0, 1, 2...).
Availability: Timer 0 - All devices
Timers 1,2 - Most but not all PCM devices
Timer 3 - Only PIC18XXX
Requires: Nothing
Examples:
// 20 mhz clock, no prescaler, set timer 0
// to overflow in 35us
set_timer0(81); // 256-(.000035/(4/20000000))
