Most significant bit in the Program Counter. (The
Program Counter is 13 bits PC[12:0])
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.
Bit in Z-register that is mapped to PCMSB. Because
Z0 is not used, the ZPAGEMSB equals PAGEMSB +

Program Counter page address: Page select, for
Page Erase and Page Write
Program Counter word address: Word select, for
filling temporary buffer (must be zero during Page
Write operation)
