问：1.ADAU1466相对于ADAU1452而言，DM0与DM1从40K扩展至80K，能支持的延时不也应该增加一倍吗，怎么还是800ms？

2.DM0与DM1的分配是由编译器决定的吗？能否人为分配DM0与DM1的使用，使得两个DM可以均衡使用， 避免一个用满而另一个却很空。

1. YES the delay time can be double if at the same sample rate.

2. DM0 and DM1 are allocate automatically by the compiler, and they are not continuous, that means it wouldn't happen that an array starts from DM0 and ends in DM1.
