Description
Most significant bit in the Program Counter.
(The Program Counter is 15 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 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).
