6.4.5 Reset Addresses
On reset, the SADDR and SADEN registers are initialized to 00h, i.e. the given and broadcast addresses are XXXX
XXXXb (all don’t-care bits). This ensures that the serial port will reply to any address, and so, that it is backwards
compatible with the 80C51 microcontrollers that do not support automatic address recognition.
