您好!
请问在C6678自带的EDMA例程里面,Poll on IPR bit 0和 Poll on IPR bit 2是什么意思?二者有什么区别呢?谢谢!

您好,
Any Ch can interrupt the CPU, IPR bit set depends on completed Ch’s TCC setting.
example: OPT.TCC=6, IPR.I6 set, then channel 6 generate the interrupt.
Elli Jiang 您好:
看到您所说的,有两个问题想请教您。
1. EDMA3个模块共有10个TC,那是不是可以推断6678能够支持10个Channnel并行传输?
2. IPR/IPRH总共有64位,那么如果TCC=6,则channel 6产生中断,那么我在open channel时是否就要将channel num设置为6?
3. CC0有16个channel,CC1和CC2则各有64个,IPR/IPRH64位,每一位对应触发一个channel interupt,但是同时只能有10个channel并行传输,那么映射到同一个TC上的不同Channel应该是顺序执行,不知这样理解对不对,还请赐教。
谢谢!!
