有哪位大佬知道，GD32F30X的系统库函数timer_init()里没有对TIMER8/TIMER11的处理，是什么原因？void timer_init(uint32_t timer_periph, timer_parameter_struct* initpara){
/* configure the counter prescaler value */
TIMER_PSC(timer_periph) = (uint16_t)initpara->prescaler;

/* configure the counter direction and aligned mode */
if((TIMER0 == timer_periph) || (TIMER1 == timer_periph) || (TIMER2 == timer_periph)
      || (TIMER3 == timer_periph) || (TIMER4 == timer_periph) || (TIMER7 == timer_periph)){
      TIMER_CTL0(timer_periph) &= ~(uint32_t)(TIMER_CTL0_DIR|TIMER_CTL0_CAM);
      TIMER_CTL0(timer_periph) |= (uint32_t)initpara->alignedmode;
      TIMER_CTL0(timer_periph) |= (uint32_t)initpara->counterdirection;
}

/* configure the autoreload value */
TIMER_CAR(timer_periph) = (uint32_t)initpara->period;

if((TIMER5 != timer_periph) && (TIMER6 != timer_periph)){
      /* reset the CKDIV bit */
      TIMER_CTL0(timer_periph) &= ~(uint32_t)TIMER_CTL0_CKDIV;
      TIMER_CTL0(timer_periph) |= (uint32_t)initpara->clockdivision;
}

if((TIMER0 == timer_periph) || (TIMER7 == timer_periph)){
      /* configure the repetition counter value */
      TIMER_CREP(timer_periph) = (uint32_t)initpara->repetitioncounter;
}

/* generate an update event */
TIMER_SWEVG(timer_periph) |= (uint32_t)TIMER_SWEVG_UPG;
}
