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 (128 words in a page
requires 7 bits PC [6:0]).
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).
Most significant bit in the program counter. (The program counter is 15 bits PC[14:0])
Most significant bit which is used to address the words within one page (128 words in a page
requires 7 bits PC [6:0]).
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).
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 7 bits PC [6:0]).
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).
