ENETx_ATCR寄存器的CAPTURE(bit11)自动清零所需时间

wwllzz

我用i.MXRT1061, 自己写的代码中需要多处用到ENETx_ATCR的CAPTURE "command" 看SDK的注释 "Add at least six clock cycle delay to get accurate time. It's the requirement when the 1588 clock source is slower than the register clock" 代码是count = 10; while(0 != (count--)){__NOP();} 我处理器跑528M,  我不需要参照这例子 只要考虑6个指令时钟周期(未必插入nop)即可吧.

建议是设置完成后，测试一下以验证是否合适
