ATmega128RFA1
Although the code for separate erase/write operations is more complex it is
recommended over the atomic operation. The erase operation can be omitted if the
target EEPROM byte already contains the value 255 (e.g. after a chip erase without the
EESAVE fuse set).
C Code Example
Assembly Code Example (Atomic Operation)
call EEPROM_write
…
void EEPROM_write(unsigned int uiAddress, unsigned char ucData)
{
}
EEPROM_atomic_write:
/* Wait for completion of previous erase/write */
while(EECR & (1<<EEPE))
/* Set up address */
EEAR = uiAddress;
EEDR = 255;
/* Write logical one to EEMPE and enable erase only*/
EECR = (1<<EEMPE) + (1<<EEPM0);
/* Start eeprom erase by setting EEPE */
EECR |= (1<<EEPE);
/* Wait for completion of erase */
while(EECR & (1<<EEPE))
/* Set up Data Registers */
EEDR = ucData;
/* Write logical one to EEMPE and enable write only */
EECR = (1<<EEMPE) + (2<<EEPM0);
/* Start eeprom write by setting EEPE */
EECR |= (1<<EEPE);
