STM8S0003K3只有一个TIM2捕获/比较中断功能，尽管有3个TIM2通道？

大家好，
我想用STM8S003K3的timer2实现衰落的LED。要求不是使用默认的PWM输出引脚而是使用普通的GPIO引脚。所以我想使用更新和比较TIM2的中断功能来写入普通GPIO引脚的高电平和低电平。这个想法类似于默认的PWM输出，但只是手动改变中断功能中GPIO的输出电平。
我的问题是为什么我只能找到1个TIM2捕获/比较中断函数映射与IRQ no。 14（IRQ no.15和16保留）。有3个TIM2通道，这意味着必须有3个独立中断功能。我可以使用保留的IRQ号码。用于中断功能？
这是STM8S0003K / F3的手册：

在第7章中，您可以找到中断向量映射。

Hi all,
I would like to realize the fading LED using timer2 of STM8S003K3. The requirement is not to use the default PWM output pin but the normal GPIO pin. So I want to use the update and compare interrupt functions of TIM2 to write High and Low of the normal GPIO pins. The idea is similar to the default PWM output but just manually change the output level of the GPIO in the interrupt function.
My question is why I can only find 1 TIM2 capture/compare interrupt function mapping with IRQ no. 14 (IRQ no.15 and 16 are reserved). There are 3 TIM2 channels which means there must be 3 independt interrupt functions. May I use the reserved IRQ no. for the interrupt functions?
Here is the handbook of STM8S0003K/F3:

In chapter 7, you can find the interrupt vector mapping.
Thanks in advance.
