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 6 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 + 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)
