Abstract
A single-wire bus (SuBUS) apparatus is provided. The SuBUS apparatus includes a master circuit coupled to a slave circuit(s) by a SuBUS. The master circuit can enable or suspend a SuBUS telegram communication over the SuBUS. When the master circuit suspends the SuBUS telegram communication over the SuBUS, the slave circuit(s) may draw a charging current via the SuBUS to perform a defined slave operation. Notably, the master circuit may not have knowledge about exact completion time of the defined slave operation and thus may be unable to resume the SuBUS telegram communication in a timely manner. The slave circuit(s) can be configured to generate a predefined interruption pulse sequence to cause the master circuit to resume the SuBUS telegram communication over the SuBUS. As such, it may be possible for the master circuit to quickly resume the SuBUS telegram communication, thus helping to improve throughput of the SuBUS.
