在调这个开发板,用的arm核,因为只有一个人调试,所以一些概念请求确认,请大家帮帮忙,看看我的理解对不。
如果收到门铃包中的doorbell info值为0x05,那么:
1.doorbell[0]_ICSR的bit5会被置为1?
2.如doorbell_ICRR[0]的ICR为6,而DBLL_ROUTR==1,则INTDST6会被触发?
3.在这个板子也就是126号中断被触发?
4.srio中断的触发当时是沿还是电平?
Allen35065:
Interrupt condition routing. Routes the interrupt request from doorbell n, bit x to one of sixteen interrupt destinations (INTDST0-INTDST15). For example, If ICS6 = 1 in Doorbell 2_ICSR and ICR6 = 0010b in DOORBELL2_ICRR, the interrupt request from doorbell 2, bit 6 is sent to interrupt destination 2.
不知道你用的什么芯片?K2H?K2E?

回复 Allen35065:
谢谢。我这个是k2h,请问它的触发方式是电平还是沿?
