7679H–CAN–08/08
The following code examples show one assembly and one C function for writing to the
EEPROM. The examples assume that interrupts are controlled (e.g. by disabling interrupts glo-
bally) so that no interrupts will occur during execution of these functions. The examples also
assume that no Flash Boot Loader is present in the software. If such code is present, the
EEPROM write function must also wait for any ongoing SPM command to finish.
Assembly Code Example
C Code Example
EEPROM_write:
void EEPROM_write (unsigned int uiAddress, unsigned char ucData)
{
}
; Wait for completion of previous write
sbic
rjmp
; Set up address (r18:r17) in address register
out
out
; Write data (r16) to data register
out
; Write logical one to EEMWE
sbi
; Start eeprom write by setting EEWE
sbi
ret
/* Wait for completion of previous write */
while(EECR & (1<<EEWE));
/* Set up address and data registers */
EEAR = uiAddress;
EEDR = ucData;
/* Write logical one to EEMWE */
EECR |= (1<<EEMWE);
/* Start eeprom write by setting EEWE */
EECR |= (1<<EEWE);
