Reading NVM Lock Bits
Erasing the Code Section
Writing a Double Code Word
Erasing the Configuration Section
Writing a Configuration Word
The algorithm for erasing all pages of the Flash code section is as follows:
The algorithm for writing two words to the code section is as follows:
The algorithm for erasing the Configuration section is as follows:
The algorithm for writing a Configuration word is as follows.
The Non-Volatile Memory Lock Byte can be read from the mapped location in data memory.
1. Write the SECTION_ERASE command to the NVMCMD register
2. Start the erase operation by writing a dummy byte to the high byte of any word location
3. Wait until the NVMBSY bit has been cleared
1. Write the DWORD_WRITE command to the NVMCMD register
2. Write the low byte of the low data word to the low byte of a target word location
3. Write the high byte of the low data word to the high byte of the same target word
4. Send IDLE character as described in section
5. Write the low byte of the high data word to the low byte of the next target word location
6. Write the high byte of the high data word to the high byte of the same target word loca-
