Description
Most significant bit in the Program Counter. (The Program Counter is 16 bits
PC[15:0])
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)
