ATmega48A/PA/88A/PA/168A/PA/328/P
address is taken from the high part of the Z-pointer. The data in R1 and R0 are ignored. The
PGWRT bit will auto-clear upon completion of a Page Write, or if no SPM instruction is executed
within four clock cycles. The CPU is halted during the entire Page Write operation if the NRWW
section is addressed.
• Bit 1 – PGERS: Page Erase
If this bit is written to one at the same time as SELFPRGEN, the next SPM instruction within four
clock cycles executes Page Erase. The page address is taken from the high part of the Z-
pointer. The data in R1 and R0 are ignored. The PGERS bit will auto-clear upon completion of a
Page Erase, or if no SPM instruction is executed within four clock cycles. The CPU is halted dur-
ing the entire Page Write operation if the NRWW section is addressed.
• Bit 0 – SELFPRGEN: Self Programming Enable
This bit enables the SPM instruction for the next four clock cycles. If written to one together with
either RWWSRE, BLBSET, PGWRT or PGERS, the following SPM instruction will have a spe-
cial meaning, see description above. If only SELFPRGEN is written, the following SPM
instruction will store the value in R1:R0 in the temporary page buffer addressed by the Z-pointer.
The LSB of the Z-pointer is ignored. The SELFPRGEN bit will auto-clear upon completion of an
SPM instruction, or if no SPM instruction is executed within four clock cycles. During Page Erase
and Page Write, the SELFPRGEN bit remains high until the operation is completed.
Writing any other combination than “10001”, “01001”, “00101”, “00011” or “00001” in the lower
five bits will have no effect.
