The EEPROM Read Enable Signal EERE is the read strobe to the EEPROM. When the correct address is set up in the EEAR Register, the EERE bit must be written to a logic one to trigger the EEPROM read. The EEPROM read access takes one instruction, and the requested data is available immediately.

When the EEPROM is read, the CPU is halted for four cycles before the next instruction is executed. The user should poll the EEWE bit before starting the read operation in the process of cloning atmega32l microprocessor memory data. If a write operation is in progress, it is neither possible to read the EEPROM, nor to change the EEAR Register.

The calibrated Oscillator is used to time the EEPROM accesses. Below Table lists the typical programming time for EEPROM access from the CPU.

The following code examples show one assembly and one C function for writing to the EEPROM. The examples assume that interrupts are controlled (for example by disabling interrupts globally) so that no interrupts will occur during execution of these functions.

The examples also assume that no Flash boot loader is present in the soft- ware. If such code is present to crack atmega32 microcontroller flash memory, the EEPROM write function must also wait for any ongoing SPM command to finish.
