8285E–AVR–02/2013
The next code examples show assembly and C functions for reading the EEPROM. The examples assume that
interrupts are controlled so that no interrupts will occur during execution of these functions.
Assembly code example
EEPROM_write:
; Wait for completion of previous write
sbic
EECR,EEWE
rjmp
EEPROM_write
; Set up address (r18:r17) in address register
out
EEARH, r18
out
EEARL, r17
; Write data (r16) to Data Register
out
EEDR,r16
; Write logical one to EEMWE
sbi
EECR,EEMWE
; Start eeprom write by setting EEWE
sbi
EECR,EEWE
ret
C code example
void
EEPROM_write(unsigned int uiAddress, unsigned char ucData)
{
/* 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);
}
