6 Single-Unit Emulation

Single-Unit Emulation is similar to the Ping Pong Emulation, but it only uses one set of Flash Sectors. Thus, the Ping Pong method cannot be used and when a full EEPROM is detected. The implemented behavior is shown in this section. Many of the functions remain the same between the two modes, and the primary differences are seen in the Erase behavior.
