关于msp430F247的IO中断唤醒

各位大侠，

      430F247在处于lpm3时，能否通过P2口的IO中断唤醒呢？我测试了下p1口是可以的，但是P2口唤醒失败。谢谢。

Maka Luo：

可以通过P1 P2口唤醒的，确认一下GPIO配置是否存在bug.

MSP430 devices have up to eight digital I/O ports implemented, P1 to P8. Each port has up to eight I/Opins. Every I/O pin is individually configurable for input or output direction, and each I/O line can beindividually read or written to.Ports P1 and P2 have interrupt capability. Each interrupt for the P1 and P2 I/O lines can be individuallyenabled and configured to provide an interrupt on a rising edge or falling edge of an input signal. All P1I/O lines source a single interrupt vector, and all P2 I/O lines source a different, single interrupt vector.The digital I/O features include:• Independently programmable individual I/Os• Any combination of input or output• Individually configurable P1 and P2 interrupts• Independent input and output data registers• Individually configurable pullup or pulldown resistors• Individually configurable pin-oscillator function (some MSP430 devices)

P2也可以中断唤醒的。
