Hyperlink手册中，有下边这两句。
Detection refers to the capturing of either hardware interrupts via the HYPERLINK_INT_I[x] pin or writes to the SW_INT register into the HW_PENDING event holding latch.
When both INTEN and SIEN are cleared to zero, the HW_EVENT[x] cannot capture any events. When both INTEN and SIEN are set to 1, both HYPERLINK_INT_IN[x] and software can trigger an event.
1.我想问一下，INT_IN[x]指外部管脚是实际存在的吗？如果我想通过这个管脚触发中断，该怎么操作？
2.SW_INT触发是硬件中断还是软件中断？
/*manually trigger the hardware event, which will generate interrupt packet to remote side*/ 这句话的意思是SW_INT写操作是手动通过软件的方式触发硬件中断吗？
