是CONFIG1寄存器决定的吗?
IRQ Enable:
This bit controls the state of the interrupt request line selected by IRQS2-0.
If this bit is set, the interrupt line goes high upon an interrupt request and will be low when there is no interrupt request.
The interrupt line will be forced to tri-state if this bit is reset.
是在这里设置吗?
