SPMCSR writing restrictions
Programming Time for Flash when Using SPM
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
The Fast RC Oscillator is used to time Flash accesses.
