Implementation of the constructor is preceded, like Or1ksimSC, by the SystemC macro.

SC_HAS_PROCESS( UartSC );
	  

The constructor calls the base class (sc_module) constructor to set the module name, saves the endianness flag in its internal state variable and clears the interrupt pending flags. The thread to handle bus I/O is associated with this module.

  SC_THREAD( busThread );
	  

The method handling data on the Rx buffer is associated with this module with static sensitivity to writes to that buffer. It is not initialized.

  SC_METHOD( rxMethod );
  sensitive << rx;
  dont_initialize();
	  

The blocking transport callback is registered for the bus socket, in the same manner as was used for the logger, LoggerSC.

  bus.register_b_transport( this, &UartSC::busReadWrite );
	  

Finally the registers (regs) are cleared.
