Description
Most significant bit which is used to address the
words within one page (128 words in a page
requires seven bits PC [6:0]).
Bit in Z-pointer that is mapped to PCMSB. Because
Z0 is not used, the ZPCMSB equals PCMSB + 1.
Bit in Z-pointer that is mapped to PCMSB. Because
Z0 is not used, the ZPAGEMSB equals PAGEMSB +
