Description
Most significant bit in the Program Counter. (The
Program Counter is 12 bits PC[11:0])
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)
