For non-interleaved access the number of channels must be set manually. It can be chosen at runtime, but the compiler cannot check whether the number of allocated channels matches the one in readn and writen.

In interleaved access the number of channels is derived from the type and must not be set manually. The number is static but the compiler checks consistency with readi and writei.
