Figure 4-6 Example Sector Erase Abort Command Flow

4.1.3.6 Sector Modify Command

The sector modify operation will erase both words in a sector of EEPROM memory followed by a reprogram of the addressed word using an embedded algorithm.

An example flow to execute the sector modify operation is shown in Figure 4-7. The sector modify command write sequence is as follows:

1.Write to an EEPROM memory address to start the command write sequence for the sector modify command. The EEPROM address written determines the sector to be erased and word to be reprogrammed while byte address bit 0 is ignored.
