標(biāo)題: ARM里面定時(shí)器0定時(shí)中斷初始化
void Time0Init(){
   T0TC = 0;
   T0PR = 0;
   T0MCR = 0x03;
   T0MCR = Fpclk/100;
   T0TCR =0x01;
   VICIntSelect = VICIntSelect & (~(1<<4));
   VICVectCntl0 = 0x20 | 4;
   VICVectAddr0 = (uint32)Timer0_ISR;
   VICIntEnable = (1<<4);
}
請(qǐng)問大佬，這段程序是怎么設(shè)置定時(shí)時(shí)間的？
