你好:
有没有人知道PSOC 4的中断延迟是什么?我运行一个4200与外部48兆赫时钟。当Itrigger与一个定时器进行中断比较时,在ISR切换输出线之前有一个800毫秒的延迟。IAM使用寄存器写,而不是生成函数之一。我的理解是,M0的潜伏期是16个周期,如果是这样的话,延迟大约只有350nS。我是不是有什么不对,或者是在这个MCU上中断得很慢?
数据表和技术参考手册的搜索没有透露任何答案。
谢谢,
史蒂芬

Hello:
Does anyone know what the interrupt latency is for the PSoC 4? I am running a 4200 with an external 48MHz clock. When I trigger an interrupt with a
timer compare, there is an 800ns delay before the ISR toggles an output line. I am using a register write, not one of the generated functions. My understanding was that latency for M0 was 16 cycles. If that was the case, the delay would only be about 350ns. Am I doing something wrong, or are interrupts slow on this MCU?
A search of the data sheet and technical reference manual did not reveal any answers.
Thanks,
Stephen
