Most significant bit in the Program Counter. (Program Counter is 14 bits
PC[13:0])
Most significant bit which is used to address the words within one page
(64 words in a page requires six/seven bits PC [5:0]).
Bit in Z-register that is mapped to PCMSB. Because Z0 is not used, the
ZPCMSB equals PCMSB + 1.
