Description of the frame:
• Byte 1: CONF ID 1 (8 bits): index of the register to be changed. The corresponding register is 300 + CONF ID X value. For example, if CONF ID
1 = 0x14 (i.e. 20 in decimal), the transmitter will change the value of the register 320.
• Byte 2: Value to give CONF ID 1: in this example, its value is contained in 1 byte
• Byte 3: CONF ID 2 (8 bits): index of the register to be changed. The corresponding register is 300 + CONF ID X value.

Following the sending of the downlink 0x41, the associated uplink 0x33 is immediately returned (see paragraph 4.1.6 for details). If the update
of the register(s) went well, the device will perform a backup and begin its restart procedure automatically. In addition, the Config bit of the
status byte (see paragraph 4.1.1.2) will be set to 1 in the next scheduled uplink frame (periodic or alarm or keep alive frame) if everything went
well.
