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 (32 words in a page requires
5 bits PC [4:0]).
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)
