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)
