How to enter timer5 interrupt in GD32F103C8T6 [Copy link]

I use the following code in my program, but I cannot enter the TIME5 interrupt. However, I can enter the interrupt by changing TIME5 to TIME2 and TIME3. Is it possible that GD32F103C8T6 does not have a TIMER5 timer? However, the manual does not mention the absence of this timer.

void timer5_init(uint16_t arr,uint16_t psc)
{
    timer_parameter_struct timer_initpara;
    rcu_periph_clock_enable(RCU_TIMER5);		/* 使能TIMER5时钟 */
    
    /* TIMER5 初始化配置 */
	  timer_deinit(TIMER5);
    timer_initpara.prescaler         = psc;						/* 时钟预分频系数 */
    timer_initpara.period            = arr;						/* 自动重装载值 */
    timer_init(TIMER5,&timer_initpara);

	  timer_enable(TIMER5);
	
	  nvic_irq_enable(TIMER5_IRQn, 3, 3);				/* TIMER5中断设置，抢占优先级3，子优先级3 */
	  timer_interrupt_enable(TIMER5,TIMER_INT_UP);	/* 使能更新中断 */ 
}

//MAIN
timer5_init(5000,12000);	/* 定时500ms*/


void TIMER5_IRQHandler(void)
{
  timer_flag_clear(TIMER5,TIMER_FLAG_UP);		/* 定时器更新中断的标识位需要手动清除 */  
	
}

GD32F103C8T6 only has four timers: timer0, timer1, timer2, timer3, and no timers 4 and 5.

Sure, just cut it off.

I don't understand what you mean. Is it possible or not? I'll check the selection manual.

This model has 4+1 timers

It should not be. Your C8 does not have it. The ones with more pins do.

C8 doesn't have it, just look at the manual and you'll know.
