Description
Most significant bit in the Program Counter. (The Program
Counter is 14 bits PC[13:0])
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 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)
