CPU 315 DP analog addressing

They cant just be using PIB because there is no resolution in that

You are right because of data consistency... but I have seen in the past reads done by reading individual bytes from the PI.
This was because the person that wrote the program didn't understand data consistency and did not notice they could indeed change the endianness in the card instead of reversing bytes in software.

But in general this shouldn't happen.
