手册中说可以将GPIO配置成CPU1的外部中断,那么能配置成CM侧的外部中断吗?如何实现?
Configuring external interrupts is a two-step process. First, the interrupts themselves must be enabled
and their polarity must be configured via the XINTnCR registers. Second, the XINT1-5 GPIO pins must
be set by selecting the sources for Input X-BAR signals 4, 5, 6, 13, and 14, respectively. For more
information on the Input X-BAR architecture, see the Crossbar(XBAR) chapter of this manual.

你好,可以看一下芯片datasheet图 7-16. External and ePIE Interrupt Sources,外部中断只能连接到CPU1或CPU2.

那就是说GPIO不能配置成为CM侧的中断源?谢谢
