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 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)
