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 PAGEMSB. Because
Z0 is not used, the ZPAGEMSB equals PAGEMSB + 1.
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)
