Overall perspective

If both the Microcontroller and the RFID reader need to share the same bank numbering

scheme, both E0 E1 values (for addressing each bank by the Microcontroller) and UID

values (for addressing each bank by the RFID reader) must be mapped.

This is performed by storing the UID of the corresponding E0E1 signals at the end of the last

memory bank as shown in Figure 10.
