3.2 Single-Unit Method

If using Single-Unit EEPROM Emulation, Figure 3-1 shows the implemented behavior.

TMS320F28P650DK9 TMS320F280039C Single-Unit Behavior Figure 3-1 Single-Unit Behavior

If the EEPROM unit is full and there is more data to be written, the EEPROM unit is erased and the new data is programmed to Flash. This process can be repeated as necessary.
