"The HCS512 decoder will automatically add a test transmitter each time an Erase All Function is done. A test transmitter is defined as a transmitter with a serial number of zero. After an Erase All, the test transmitter will always work without learning and will not check the
synchronization counter of the transmitter. Learning of any new transmitters will erase the test transmitter." -- [HCS512 datasheet](https://www.microchip.com/content/dam/mchp/documents/MCU08/ProductDocuments/DataSheets/40151E.pdf)
