Description
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-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 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)
