Write
To write a location, the user must write the address into EEAR and the data into EEDR. If the
EEPMn bits are 0b10, writing the EEPE (within four cycles after EEMPE is written) will trigger
the write operation only (programming time is given in Table 1). The EEPE bit remains set
until the write operation completes. If the location to be written has not been erased before
write, the data that is stored must be considered as lost. While the device is busy with pro-
gramming, it is not possible to do any other EEPROM operations.
The calibrated Oscillator is used to time the EEPROM accesses. Make sure the Oscillator fre-
quency is within the requirements described in
Register – OSCCAL” on page
The following code examples show one assembly and one C function for erase, write, or
atomic write of the EEPROM. The examples assume that interrupts are controlled (e.g., by
disabling interrupts globally) so that no interrupts will occur during execution of these
functions.
