Description
Most significant bit in the Program Counter. (The
Program Counter is 12 bits PC[11:0])
Most significant bit which is used to address the
words within one page (64 words in a page requires
six bits PC [5:0]).
Bit in Z-register that is mapped to PCMSB. Because
Z0 is not used, the ZPCMSB equals PCMSB + 1.
