init timer for ppi.c

基于ADI blackfin处理器的范例程序

#include "system.h"

void initTimer()
{
	
	
		*pTIMER_DISABLE = TIMDIS0;		// disable timer 2
		*pTIMER0_PERIOD = 525;
		*pTIMER0_WIDTH  = 1; 
		*pTIMER0_CONFIG   = PWM_OUT | PULSE_HI | PERIOD_CNT | CLK_SEL | TIN_SEL | IRQ_ENA | EMU_RUN;
		*pTIMER_ENABLE = TIMEN0;
		asm("ssync;");
}
