Instruction/Operation
Write EEPROM Memory
Write EEPROM Memory Page (page access)
Write Lock bits
Write Fuse bits
Write Fuse High bits
Write Extended Fuse Bits
Notes:
If the LSB in RDY/BSY data byte out is ‘1’, a programming operation is still pending. Wait until
this bit returns ‘0’ before the next instruction is carried out.
Within the same page, the low data byte must be loaded prior to the high data byte.
After data is loaded to the page buffer, program the EEPROM page, see
242.
1. Not all instructions are applicable for all parts.
2. a = address
3. Bits are programmed ‘0’, unprogrammed ‘1’.
4. To ensure future compatibility, unused Fuses and Lock bits should be unprogrammed (‘1’).
5. Refer to the corresponding section for Fuse and Lock bits, Calibration and Signature bytes
6. Instructions accessing program memory use a word address. This address may be random
