Notes:
Depending on CKSEL Fuses, a valid clock must be present. The minimum low and high periods
for the serial clock (SCK) input are defined as follows:
Low: > 2 CPU clock cycles for f
High: > 2 CPU clock cycles for f
When writing serial data to the ATmega640/1280/1281/2560/2561, data is clocked on the rising
edge of SCK.
When reading data from the ATmega640/1280/1281/2560/2561, data is clocked on the falling
edge of SCK. See

programming the EEPROM, an auto-erase cycle is built into the self-timed programming oper-
ation (in the Serial mode ONLY) and there is no need to first execute the Chip Erase
instruction. The Chip Erase operation turns the content of every memory location in both the
Program and EEPROM arrays into 0xFF.
