SPMCSR writing restrictions
Table 29-3.
Notes:
All other addresses are reserved for future use.
Writing any other combination than “100001”, “010001”, “001001”, “000101”, “000011” or
“000001” in the lower six bits will have no effect.
SPMCSR is locked for writing under the following conditions:
• One or more of the bits 5:0 in SPMCSR is set to 1
• During EEPROM write (status bit EEWE in EECR is set)
SPMCSR will be cleared at the following events:
• on completion of successful execution the following instructions:
• six cycles after writing SPMCSR if any other or no LPM/SPM is executed
