Description
Most significant bit in the Program Counter. (The Program Counter is 14 bits
PC[14:0])
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
