Notes:
The Store Program Memory Control and Status Register contains the control bits needed to con-
trol the Boot Loader operations.
• Bit 7 – SPMIE: SPM Interrupt Enable
When the SPMIE bit is written to one, and the I-bit in the Status Register is set (one), the SPM
ready interrupt will be enabled. The SPM ready Interrupt will be executed as long as the SPMEN
bit in the SPMCSR Register is cleared.

Description
Most significant bit in the Program Counter. (The
Program Counter is 17 bits PC[16:0]).
Most significant bit which is used to address the
words within one page (128 words in a page
requires seven bits PC [6:0]).
Bit in Z-pointer that is mapped to PCMSB. Because
Z0 is not used, the ZPCMSB equals PCMSB + 1.
Bit in Z-pointer that is mapped to PCMSB. 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).
