1. The Z-register is only 16 bits wide. Bit 16 is located in the RAMPZ register in the I/O
2. Z0: should be zero for all SPM commands, byte select for the (E)LPM instruction.
3. See “Addressing the Flash During Self-Programming” on page 280 for details about

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 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)
