The rightmost bits of the register that are not used to form the address, which are bits 61-63 in the doubleword case and bits 52-63 in the 4K-byte case, are ignored but should contain zeros; otherwise, the program may not operate compatibly in the future."
That has to be one of the worst hardware implementation decisions of all time! How much silicon would it have taken to generate PIC 006 if the ignored address bits are not zero?
