This entity provides a very simple 1-wire master to read out the id of a 1-wire device. It does not support busses with more than one device and does not check if the device is really present. Other commands than READ ROM are not supported.

The entity provides one tristate port to connect to the one wire bus. The data is output on a data port along with an address (counting from 1 to 4, according to TrbNetAddresses) and a write signal. This output port will be connected to TrbNetRegIO.

The temperature of the sensor is also read out and provided on a 12 bit port in the sensors native data format (1/16th degree celsius in case of an DS18B20)

This output port will be connected to TrbNetRegIO and not directly to TrbNetAddresses, since we may want to be able to read out this ram from another point.
