This makes it possible to record new code to from the last written address. To allow this, the system must be configured in programming mode, becoming different in terms of the reception / sending of the transponders 2 detected. From now on, a management application is expected to indicate the commands to be sent to a specific transponder 2 (identified by its IDTR identifier). These commands are generated from the new compiled code that is to be stored in transponder 2. Transponder 2 captures said commands and stores them in the memory address designated for it. Finally, a status register is changed that indicates that you have to keep looking at the new code from that address. From this moment the transponder 2 will enjoy a new functionality implemented through programming via radio.
