请教一下，下面的程序能实现C6713的1s的定时么？
//stop the timer
*(unsigned volatile int *)TIMER0_CTRL &= 0xff3f;
//set the work mode
/* Use CPU CLK/4 */
*(unsigned volatile int *)TIMER0_CTRL |= 0x200;
//set the period
*(unsigned volatile int *)TIMER0_PRD |= 0xffffffff;
//start the timer
*(unsigned volatile int *)TIMER0_CTRL |= 0xC0;
//the number of timer input clock cycles to count
number = *(unsigned volatile int *)TIMER0_COUNT;
timer=1000000*225/4;
while ((number - *(unsigned volatile int *)TIMER0_COUNT) < timer);
