Following the sending of the downlink 0x41, the associated uplink 0x33 will be immediately returned (see detail in section 4.1.6). If the update
of the register (s) went well, the product will save and start its restart procedure automatically. In addition, the Configuration bit of the status
byte (see section 4.1.1.2) will be set to 1 in the next scheduled upstream frame (periodic, alarm or life frame).
